查询词典 communication protocols

In different scenarios factors related with these characteristics will affect the performance of routing protocols in different way. So it is critical to understand the influence of different factors precisely for the purpose of achieving best cost efficiency. Most of the routing protocols depend on broadcasting to disseminate the route request message. But broadcast can always incur broadcast storm problems and consume considerable amount of network resources.

因此，无线自组织网络中路由查询的效能取决于两个方面：第一，路由协议设计能否满足上述第一个方面的静态特性需求，这也是无线自组织网络路由技术研究领域内受到广泛关注的热点；第二，能否准确把握网络中各种因素对路由协议性能的影响，使路由参数配置以及路由策略选择与具体的网络环境相适配，在路由查询效率与开销之间寻得最佳平衡。

In this paper, the concept of network security and security structures of OSI and Internet is introduced, and various threats confronting the computer network are also discussed. Several kinds of network information security technologies, including firewall technology, virtual private network, intrusion detection system, data encryption technology, identity authentication and security protocol etc. are also examined. The security of internal network is the biggest problem in the construction of each network. The solution to this problem lies in setting up a firewall. The theory of a firewall and the approach to its actualization is studied. Intrusion detection system, an important part of the computer network security system, has gained extensive attention. IDS monitors the computer and network traffic for intrusion and suspicious activities. It not only detects the intrusion from the extranet hacker, but also the intranet users. The emergence of virtual private network paves the way for realizing secure connection of LAN quickly and at a relatively low cost. The concept, function, key techniques, including the tunnel technology, and the ways to realize VPN are expounded in this paper. Also introduced is the data encrypt network technology, which is called the soul of computer network security, such as digital digest, digital signature, digital certificate, digital encrypt arithmetic and so on. At the same time, the principle and the process of implementing network security by digital certificate and digital signature, the basic principle and characters of security protocols, and finally, three of the security protocols, concerning the security problems in network, IPsec, SLL and SET are analyzed in detail Computer network system should be a system of dynamic defence, both dynamic and static, passive as well as active, and even offensive, combined with management and technology.

Security analysis for two quantum key distribution protocols was presented by using EPR pair and complete Bellstate measurements. It is also shown that those two protocols are totally equivalent from the point of view of the topological structures on how to measure the corresponding qubits at random.

The UPnP technology is typical in all home network middleware technologies. It bases on TCPIIP protocols and WEB technology, makes use of some existing network technologies and protocols, such as XML, SOAP, GENA and so on. With UPnP, a device can dynamically join a network, obtain an IP address, convey its capabilities and learn about the presence and capabilities of other devices--all automatically.

Authentication Test is a new type of analysis and design method of security protocols based on Strand space model, and it can be used for most types of the security protocols. However, as a Strand space model, it is inclined to be used for the proof of correctness, and is relatively weaker for incorrectness analysis.

认证测试是一种新型的在Strand空间模型基础上发展而来的安全协议分析与辅助设计技术，可用于大部分协议的关联属性的分析；但是与Strand空间模型一样，它主要用于协议正确性证明，在协议为何不正确以及如何进行改进这个问题上处理分析能力较弱。
