a r X i v :q u a n t -p h /0401078v 1 14 J a n 2004N-Partner Secure Direct Communication Based on Quantum NonlocalityHua L¨uDepartment of mathematics and physics,Hubei polytechnic university,Wuhan,430068,ChinaQing-Yu CaiWuhan Institute of Physics and Mathematics,The Chinese Academy of Sciences,Wuhan 430071,ChinaA multipartner secure direct communication protocol is presented,using quantum nonlocality.Security of this protocol is based on ‘High fidelity implies low entropy’.When the entanglement wassuccessfully distributed,anyone of the multipartner can send message secretly by using local opera-tion and reliable public channel.Since message transfered only by using local operation and publicchannel after entanglement successfully distributed,so this protocol can protect the communicationagainst destroying-travel-qubit-type attack.Since the pioneering work of Bennett and Brassard published in 1984[1],different quantum key distribution pro-tocols has been presented [2-15].Different from the key distribution protocol,some quantum direct secure communi-cation (QDSC)protocols have been shown recently [16-18],which permits important message can be communication directly without first establishing a random key to encrypt them.However,these protocols [1-18]only permit message transferred from the sender (Alice)to the receiver (Bob).In reference [19],a protocol was presented that allows Alice and Bob communicate with each other coequally.When Alice want to secretly send message to two or more persons at the same time,the protocols based on entanglement of two qubit are feeble.In this paper,we show a secure direct communication protocol that allows multipartner instantaneously communicating secretly by using .T he multipartner protocol .Three qubit can be entangled in a Greenberger-Horne-Zeilinger (GHZ)state |φ0>[20]|φ0>=12(|0>|0>|0>+|1>|1>|1>),(1)where |0>and |1>are the up and down eigenstate of the σz ,the photon polarization operator.Suppose three partners,Alice ,Bob and Charlie,want to secretly communicate together.First of all,Alice prepares three qubits in a GHZ state |φ0>.She keeps one qubit and sends each of the other two qubits to Bob and Charlie.When Bob and Charlie receive the travel,both of them send a classical signal as receipt to Alice through public channel.When Alice receives their receipt,she states this is a message mode in public.Then Alice,bob and Charlie perform a measurement in basis B z ={|0>,|1>}.If Alice’s measurement is |0>(|1>),then she knows Bob and Charlie’s measurement outcome are |0>(|1>).When she wants to send a classical bit ‘0’to Alice and Bob,if her measurement is |0>,then she ‘say yes’in public.If her measurement is |1>,then she ‘say no’through public channel to both Bob and Charlie.When Alice wants to send a logical ‘1’to Bob and Charlie,if her measurement outcome is |0>,she ‘say no’in public.Else,she ’say yes’to Bob and Charlie through public channel.By default,Alice,Bob and Charlie are inmessage mode and communicate the way described above.With probability c ,Alice switches to control mode.In control mode.when Alice receives Bob and Charlie’s receipt,she performs a measurement randomly in basis B z or B x ={|+>,|−>},where |+>=12(|0>+|1>),|−>=12(|0>−|1>).Then she announces her measurement outcome.Bob and Charlie also switch to control mode.They perform measurement in the same basis Alice used.Iftheir measurement outcomes do not coincide when both of them use the basis B z ,there is an eavesdropper-Eve in linear.When they use the basis B x ,their measurement outcome should be in the states |±>.Usingσx |+>=|+>,σx |−>=−|−>,(2)when the products of σA x (Alice),σB x (Bob),and σC x (Charlie)is −1,there is an Eve in line.The communicationstops.Else,this communication continues.Security proof .To effectively eavesdrop Alice’s information,Eve has to distinguish what state Bob or Charlie obtains since she has no access to Alice’s qubit.It has been presented that there two inequivalent forms of three qubits entangled state [21].One is namely GHZ state.The other is |W >|W >=13(|1>|0>|0>+|0>|1>|0>+|0>|0>|1>).(3)1These two different states can not be converted by means of SLOCC[21].After Eve’s attack,the state will become a product state or still is a GHZ-type state|φ1>=12(|0>|0>|0>−|1>|1>|1>),(4)|φ2>=12(|1>|0>|0>+|0>|1>|1>),(5)|φ3>=12(|1>|0>|0>−|0>|1>|1>),(6)|φ4>=12(|0>|1>|0>+|1>|0>|1>),(7)|φ5>=12(|0>|1>|0>−|1>|0>|1>),(8)|φ6>=12(|0>|0>|1>+|1>|1>|0>),(9)|φ7>=12(|0>|0>|1>−|1>|1>|0>).(10) Together with|φ0>,these eight states compose a complete base.Suppose the state|φ0>becomesρunder Eve’s attack.ρmust be a linear combination of|φi>.Thefidelity[22]ofρand|φ0>isF(|φ0>,ρ)=tr<φ0|ρ|φ0>‘Highfidelity implies low entropy.’Assume F(|φ0>,ρ)2=1−γ.The information fromρis bounded by the Holevo quantity,χ(ρ)[23].Fromχ(ρ)=S(ρ)− i p iρi,(12)we know that S(ρ)is the upper bound of the information Eve can gain.The entropy ofρis bounded above by the.The entropy ofρmax isentropy a diagonal density matrixρmax with diagonal entries1−γ,γ7γS(ρmax)=−(1−γ)log(1−γ)−γlogthere is S(ρmax)=0,i.e.,Eve can get no information from the communication.When S(ρmax)>0,i.e.,Eve can get some information from the communication,she has to face a nonzero risk to be detected.This protocol is quasisecure for a direct communication but is secure for a quantum key distribution protocol. Also,multipartner can communication using two-particle entanglement network.However,our protocol can provide a secure direct communication between three partners.Actually,Alice,Bob and Charlie are coequal in this protocol. So they can communicate with others coequally when the entanglement was successfully shared.Consider there are N partner want to communicate securely.They can share N-particle GHZ states.With local measurement and classical message,they can communicate securely.When N-particle entanglement was successfully shared,no qubit has to be exchanged in quantum channel.Then the destroying-travel-qubit-type attack[19]is invalid.Entanglement of three photons has been demonstrate experimental[24].And the quantum nonlocality of four photons entanglement has already been reported[25].The experimental feasibility of our protocol,can be realized with today’s technology.I.REFERENCES.[1]C.H.Bennett,and G.Brassard,in Proceedings of the IEEE international Conference on Computers,Systems and Signal Processing,Bangalore,India(IEEE,New York,1984),pp.175-179.[2]A.K.Ekert,Phys.Rev.Lett.67,661(1991).[3]C.H.Bennett,G.Brassard,and N.D.Mermin,Phys.Rev.Lett.68,557(1992).[4]C.H.Bennett,Phys.Rev.Lett.68,3121(1992).[5]C.H.Bennett and S.J.Winsner,Phys.Rev.Lett.69,2881(1992).[6]L.Goldenberg and L.Vaidman,Phys.Rev.Lett.75,1239(1995).[7]B.Huttner,N.Imoto,N.Gisin,and T.Mor,Phys.Rev.A51,1863(1995).[8]M.Koashi and N.Imoto,Phys.Rev.Lett.79,2383(1997).[9]D.Bruss,Phys.Rev.Lett.81,3018(1998).[10]W.Y.Hwang,I.G.Koh,and Y.D.Han,Phys.Lett.A244,489(1998).[11]H.-K.Lo and H.F.Chau,Science283,2050(1999).[12]A.Cabell,Phys.Rev.Lett.85,5635(2000).[13]A.Beige,B.-G.Englert,C.Kurtsiefer,and H.Weinfurter,Acta.Phys.Pol.A101,357(2002).[14]B.S.Shi,Y.K.Jiang,and G.C.Guo,Appl.Phys.B:Laser Opt.B70,415(2002).[15]P.Xue,C.F.Li,and G.C.Guo,Phys.Rev.A65,022317(2002).[16]A.Beige et al.,Acta Phys.Pol.A101,357(2002).[17]K.Bostroem and T.Felbinger,Phys.Rev.Lett.89,187902(2002).[18]Fu-Guo Deng,Gui Lu Long,and Xiao-Shu Liu,Phys.Rev.A68,042317(2003).[19]Qing-yu Cai,arXiv:quant-ph/0309108(unpublished).[20]D.M.Greenberger,M.A.Horne,and A.Zeilinger,in Bell’s Theorem,Quantum Theory,and Conceptions of the Universe,edited by M.Kafatos(Kluer,Dordrecht,1989),p.69.[21]W.Duer,G.Vidal,and J.I.Cirac,Phys.Rev.A62,062314(2000).[22]C.A.Fuchs,arXiv:quant-ph/9601020;H.Barnum,C.M.Caves,C.A.Fuchs,R.Jozsa,and B.Schumacher, Phys.Rev.Lett.76,2818(1996).[23]M.A.Nielsen and I.L.Chuang,Quantum computation and Quantum Information(Cambridge University Press,Cambridge,UK,2000).[24]D.Bouwmeester et al.,Phys.Rev.Lett.82,1345(1999).[25]J.-W.Pan et al.,Nature(London)403,515(2000).3。

Fortinet 完整安全解决方案概述说明书
Complete Small and Midsize Business Protection Consolidated Management. Proven Security. Maximum Value.Executive SummaryWith 43% of attacks in 2019 targeting small and midsize businesses (SMBs),1 security is no longer a topic business leaders can ignore yet remains one of the most intimidating subjects for many leaders to tackle.New technologies and working models expose new risks, meaning effective security must be complete security. The good news is security has gotten much better. Leading security vendors like Fortinet are continually validated by third-party testing groups to effectively prevent threats across a broad range of tactics. Built off the same underlying code and taking advantage of custom-built hardware, the Fortinet Security Fabric effectively stops attacks and automatically communicates to reduce false alerts and maintenance. By taking advantage of a single vendor approach, workloads drop, operational efficiency increases, and securing your business suddenly becomes much easier.Designed to maximize simplicity, Fortinet Small and Midsize Business Security Solutions deliver a path to complete protection. Clear ROI is delivered without sacrificing security with tight integration, automation, and visibility across your entire cybersecurity footprint to improve effectiveness, reduce cycles, and scaleas your company grows. Cloud-based, centralized management simplifies ongoing operations with business-driven rules and policies so you can quickly consume new technology while keeping your business safe from attack.Fortinet SMB Security SolutionsSecure Office NetworkingAt the heart of any cybersecurity solution is its ability to protect the business from incoming network attacks. Next-generation firewalls (NGFWs) understand howthe combination of the user, the device they’re using, and the application they’re interacting with should behave, analyze the traffic and ultimately understand how it should be transmitted, replacing the need for traditional routers.The NGFW is just part of the solution. For traffic to ultimately reach the user, or for the user or device to reach the internet, traffic must travel through two key devices that help scale network access around the office—switches for wired devices and wireless access points (APs) for wireless connectivity.The combination of these three devices—NGFW, switch, and wireless AP—form the core of network connectivity. Businesses need both high performance and strong security from their network, and with Fortinet, you can have both and enable safe access to the cloud with built-in Secure SD-WAN at no additional cost.nn FortiGate: The most cost-effective NGFW for performance and protection3 with built-in Secure SD-WAN to better control network performance to cloud-based applications and secure traffic.Fortinet SMB Security Solutions Provide Affordable, Complete Securitynn Secure Office Networking: Protect the traditional office network while enabling a hybrid work force.nn Endpoint and RemoteUser Protection:Enable your users to work from anywhere with leading endpoint security and secure access.nn Secure Cloud Applications and Email:Build out the secure cloud-connected office and take full advantage of the cloud.nn Cloud-based Management and Analytics:Streamline and simplify security, management, and ongoing operations.SOLUTION BRIEFTwo-thirds of organizationsare actively consolidatingthe number of cybersecurityvendors with which they dobusiness for better operationalefficiency and cost savings.2nn FortiAP: High-performance, Wi-Fi 6 ready APs ensure strong connectivity even in dense, highly populated environments.n FortiSwitch: Stackable, Power over Ethernet (PoE) functionality delivers performance and scale to meet any need.nUnified security across firewalls, switches, and wireless access pointsBy consolidating Layer 7 routing and multiple security services into a single, industry-leading NGFW, many business are able to reduce the cost of multiple licenses and the oversight needed to maintain a strong security position as multiple needs are solved by one. With Fortinet, this exercise in simplicity extends even further thanks to proprietary technology that allows administrators to extend this security to FortiSwitches and FortiAPs, creating a truly secure connectivity environment for the office. FortiGate NGFW consolidates security functions*n Anti-malware/antivirus: Prevents basic malware, threats, and bot activitynn Intrusion prevention (IPS): Uncovers advanced threats hidden deep within packets missed by basic antivirusnn Virtual private network (VPN): Creates an encrypted, private communication through the public web between user and office network nn Web and content filtering: Enable SafeSearch and block traffic to explicit and malicious websitesn*For a complete list of security services available to the FortiGate, please discuss with your Fortinet representative or authorized partner.Simple, high-performance connectivity with built-in Secure SD-WANAs your business grows and more users and devices need to connect in and around the office and to the cloud, network bottlenecks can quickly hinder productivity. Fortinet FortiGate NGFWs, along with FortiAP wireless access points and FortiSwitches, provide industry-leading network connectivity while maintaining enterprise-grade security. Additionally, built-in Secure SD-WAN helps improve cloud-based application performance over multiple paths while retaining strong security. Fortinet Secure SD-WAN enables fast access to cloud-based applications and high-quality experiences in multi-cloud environments by self-healing for data loss and network speed before it affects the application. As an integrated component of the FortiGate, organizations are protected against the latest risk exposures and evolving sophisticated attacks included for no additional cost and without the headache of configuring and managing another point product.Endpoint Protection and Remote User ProtectionAs workers increasingly move outside the traditional office environment on a permanent or semi-permanent basis, the need for strong endpoint protection, detection, and remediation increases in importance. With a combination of FortiClient and FortiEDR, businesses can obtain rich visibility and control over endpoint hygiene, network access, and discover and prevent malicious attacks like ransomware from spreading across the network.Endpoint visibility and controlFortiClient was designed to natively integrate with the larger Fortinet Security Fabric. Tight integration with the FortiGate NGFW allows administrators to easily drill into user devices and assess risk level, network access, and ensure content filtering policies remain consistent even when users are offline.Secure access and VPNFortiClient also includes a free client VPN service to ensure users are protected anywhere they log in. With built-in auto-connect and split-tunneling capabilities, there is no need to purchase a standalone VPN solution and further complicate the environment. Real-time breach protection and ransomwareWith FortiEDR, businesses can raise their level of preparedness and block exploits, stop breaches, data exfiltration, and ransomware attacks automatically, without disrupting business operations. FortiEDR brings multilayer detection and prevention technology such as machine learning (ML), patented code-tracing technology, and automated response and remediation procedures.Secure Cloud Applications and EmailThe cloud offers businesses a wealth of efficiency and simplicity while trading out control. Protecting the information stored within these services often falls unknowingly on the business rather than the application vendor. With Fortinet, administrators can build out a secure cloud-connected office by securely accessing cloud-based applications with SD-WAN, virtual firewalls to protect data across AWS, Azure, GCP, and Oracle Cloud, and ensuring email is protected when using popular platforms such as Microsoft 365 and Google Mail.Copyright © 2021 Fortinet, Inc.

Built for the cloud, FortiGate VMs deliver protection across public, private, and multi-cloud environments.n n Safely leverage cloud benefits of scalability, metering, and time to market with cloud-native securityn n Seamlessly scale without increasing operational burdensn n Flexible consumption models include licensing and on-demand usage modelsEnhanced email securityEmail continues to be the top method of attack used by attackers to dupe unsuspecting users into running malicious files and clicking on malicious links through phishing and other business email compromise (BEC) schemes. FortiMail Cloud offers unparalleled protection to remove these risks from your workforce and provide additional protection to popular email platforms such Microsoft 365 and Google Mail.Cloud-based Management and AnalyticsSecurity works on the premise of understanding what is good, what is not, and responding accordingly. When different vendor products perceive a threat differently, conflicts arise, leaving the burden of analysis on the administrator. With Fortinet,automated information sharing across the solution and the ability to manage it from a single pane of glass help streamline and simplify security, management, and ongoing operations.Cloud-based managementCentralized, cloud-based management of the complete SD-Branch (NGFW, AP, Switch, SD-WAN, Security), FortiGate Cloud, is included with the purchase of the FortiGate NGFW. From here, administrators can simplify deployments, management, and troubleshooting with actionable insights and visual reports of their basic network.As locations and implementations grow and/or additional Fortinet security products are installed, businesses can easily upgrade to FortiManager and FortiAnalyzer to centralize all administrative tasks.A Solid Security Foundation on Which To Build Y our BusinessTechnology both enables productivity and increases the risk of a breach as the attack surface grows. Looking across the security landscape, there are many options and closer inspection regularly finds critical holes in a vendor’s offerings such as:n n Limited solutions forcing you to purchase from multiple vendors to protect everything and stitch them together yourself n n Confusing implementation and management that result in ineffective protectionn n Expensive solutions that claim to protect everything and leave no budget for anything elseFortinet SMB Security Solutions are engineered to scale as your business grows and give you the confidence of investing in a market-leading security platform designed to reduce workloads while maintaining security. Only Fortinet offers this breadth of small business offerings validated by security experts.Curious where to start?

Cloze test（1%×15=15%）Alexander Graham Bell is often thought to be the father of the telephone. However, there were many other scientists, like Elisha Gray and Antonio Meucci, who also developed a talking telegraph(电报). It is not a simple thing to 21 who is the ‘father’ of something. The name often goes to the scientist of the most useful work, not to the one with the 22 idea. This is exactly what happened with the telephone.There has been a 23 about who really developed the telephone. People have written articles and books about the subject. It is known that Bell got the patent (专利) for designing the telephone in 1876. He was the first to get the patent but he was not the first to think of the 24 of a telephone. Antonio Meucci, an Italian scientist, 25 building a talking telegraph in 1849. In 187l, he got an official document that could prove he designed the machine. In later years, because of some 26 , Meucci couldn’t get a new document. His name in the history of the telephone was then 27 until his work was honored (被授予表彰) again on June 11, 2002.Some studies on the patent application (申请) of the telephone have made things even more 28 . Researchers say that Elisha Gray, a(n) 29 at Oberlin College, and Bell applied for the patent of the telephone on the same day. These gentlemen didn’t actually 30 the Patent Office —their lawyers (律师) did. Researchers find in records that Bell’s lawyer went to the office 31 . The date was February 14, 1876. He was the fifth to get into the office that day and Gray’s lawyer was the 39th. As the result, Bell got the patent and Gray’s work was not honored. 32 , many people don’t believe this story. They think that there had to be some 33 or unfair (不公正的) actions by people working at Patent Office, and 34 even by Bell himself.This long discussion is 35 not coming to its end. But this question may not matter at all. After all, we could live in a very different world without any of the three scientists’ great work.21. A. Think B. decide C. predict D. imagine22.

He likes going canoeing in the morning.BI was born missing my left arm. In 1986, at 18 months, I was fitted with a prosthetic (义肢) device, a decision made by my parents and doctors so that I would develop “normally”.I spent my entire childhood and adolescence trying to fit in. I did just about anything to ease the pains of the stares and pointing fingers from my classmates. By the time I was 8, I had no self-confidence, and the hand I was wearing was making it harder for me to fit in. So I decided I was better off without one. I didn’t need anyone to fix me.To prove that I wasn’t limited by my disability, I developed a love for all sports, in particular swimming. I was selected to my first Australian women’s swimming team at age 13 and successfully represented my country for eight years. I realized I’d made a name for myself because of my disability.I taught myself how to be comfortable in a society filled with insecurities (不安全). So when I was first contacted in 2021 by Covvi, a company trying to create the world’s most advanced bionic (仿生的) hand, I was a bit surprised. They asked me to trial the hand and, if possible, to become a patient advocate (病人权益维护者). Initially, I said no. Then, curiosity got the better of me.While I was busy advocating for disability rights, a new generation of leaders, like Amy Purdy and Nick Vujicic, used the power of technology and social media to display wheelchairs or artificial limbs without explanation. People feared disability less. Society was beginning to see a person first, and their disability second.Viewing disability through a social lens also meant acknowledging (承认) that a person is more disabled by their environment and the discrimination (歧视) of others than by their actual disability. As those conversations shifted, I realized that there was an opportunity to use technology to change the future generations’ view on disability. In July 2022, I decided to trial the hand.The role of patient advocate is a huge honor. Through sharing my journey, I’m able to reach thousands of other people who would benefit from its extraordinary capabilities (能力). That’s why I wear a bionic hand — not because I’m broken, but because I have an opportunity to increase the human capabilities that already exist.41. When was the author fitted with a prosthetic device?A. At 18 months old.B. At 8 years old.C. In her adolescence.D. In 2022.42. From Purdy and Vujicic, the author learned ______.A. more people accepted their limitsB. the disabled needed a friendlier environmentC. social media allowed the disabled opportunitiesD. technology changed people’s attitudes to disability43. What does NOT make it more difficult for the disabled to fit in?A. People’s fear of disability.B. Others’ discrimination of the disabled.C. Their actual disability.D. The unfriendly environment.44. Why did the author finally decide to trial the bionic hand in July2022?A. She believed it would fix her disability.B. She wanted to become a patient advocate.C. She realized the power of technology.D. She wanted to prove her success in swimming.45. Which of the following words can best describe the author?A. intelligent and braveB. warm-hearted and patientC. responsible and strong-willedD. independent and innovativeCIf your phone needs a software upgrade, you would likely run the installations (安装)when it’s fully charged. Otherwise, your phone and its software would not work properly. A new study finds human energy systems operate in a similar fashion: Our metabolisms (新陈代谢) likely work best in the morning when our bodies are fresh and fully charged.The research, based on a seven-year dietary analysis of 50,000 adults, found that body weight, measured by BMI (body mass index), is related to when we eat and how often we eat.Specifically, people who eat larger breakfasts and adopt an 18-hour overnight fast (禁食), say from 1 pm to 7 am,have the lowest body weights. Those who ate more than three meals, or three meals plus snacks, had higher BMIs.Those who ate later in the day, after 6 pm, compared to having the largest meal at breakfast or lunch, had higher body weights. The Loma Linda University researchers suggest that 18 to 19-hour overnight dietary fasts restart our metabolisms to help our bodies burn calories efficiently (有效地).Lead author says this process (进程）makes sure that our energy intake correlates (相互关联）with energy output, instead of energy reserves or enlarged fat cells. Different from popular belief, these extended overnight fasts seem to help start metabolic work.The author also finds meals eaten in the evening, compared to those eaten in the morning, result in a hypoglycemic response (血糖升高), or raised blood sugar, which happens when insulin (胰岛素) can’t deal with glucose (葡萄糖) into energy. Like a clog (阻塞) in a machine, extra glucose slows our bodies’ metabolic process down. Depending on your goals and health situation, you may consider taking more calories in the morning when insulin work is most efficient.So, let’s say you take 1,500 to 1,800 calories a day. Instead of splitting 500 to 600 calories evenly (均等的) at each meal, you could experiment with eating 600 to 700 calories for breakfast, 600 to 700 calories for lunch and a light 300-to 400-calorie dinner. If you’re looking to lose 10 pounds or change the early stages of Type 2 diabetes (糖尿病) completely, the 18-to 19-hour overnight fast might work well for you. This could mean eating a larger breakfast, a medium-sized lunch and no dinner at all.46. What is the new study based on?A. A dietary analysis.B. An experiment in the lab.C. A survey on children.D. A famous newspaper.47. What kind of eating pattern is connected with the lowest body weight?A. Eating more than three meals a day.B. Having the largest meal at dinner.C. Eating a large breakfast and fasting overnight.D. Having snacks throughout the day.48. What happens when we eat in the evening?A. Our metabolisms speed up.B. We have a hypoglycemic response.C. Our bodies burn calories more efficiently.D. We have an high blood sugar level.49. How can we rearrange our meals for better results?A. Take in more calories at dinner.B. Split calories evenly among all meals.C. Take in more calories in the morning.D. Skip breakfast and have a big lunch.50. What is the best title for this article?A. Can Skipping dinner help you lose weight?B. How to lose weight or reverse early Type 2 diabetes?C. How to control the normal blood sugar level?D. Can exercising a lot make your body fully charged?卷Ⅱ主观题（满分50分）Please write the answers on the answer sheet. (请将此卷答案写在答卷纸上）Ⅳ. VocabularyA. Complete each sentence with proper words.
