Finally, the strict formal analysis is made for ZDB protocol(1999) proposed by Zhou et al. With this new method, as a result there exists 2 possible attacks in the ZDB protocol under non-secrecy channels: leakiness of secret information and reply attacks.

最后本文用新方法对Zhou等人(1999)提出的 ZDB协议进行了严格的形式化分析，结果发现该协议在非保密通道下存在两个可能的攻击：保密信息泄露和重放攻击。

The data capture mainly gathers the data from the network. Protocol analysis can analyse every segment of the data packet according to protocol standard. Data recover can recover all the data of the application layer of the TCP connection. IP spoofing can construct all kinds of packets and realize the network attack. Real-time interruption can interrupt the TCP connection of Both sides of communication as the third party. Fire wall can realize network access control. Then the system can protect the network information safety from many aspects.

数据捕获主要完成从网络采集数据的功能；分析还原包括协议分析和数据还原两部分内容，协议分析可以对捕获到的数据包按照网络协议规范分别进行各协议字段分析，数据还原功能可以将每条TCP连接中传输的所有应用数据进行重新组合，还原出原来数据的内容；IP欺骗指构造各种功能的数据包，实现网络攻击；实时阻断指第三方实时阻断通信双方的TCP连接，禁止他们进行数据通信；防火墙主要实现网络访问控制，保护内部子网的功能。

We demonstrate that our protocol performs nearly as well as an ideal protocol that is given perfect channel-state information.

They allow that the backend server could delegate the reader to identify the tag information. But the Fouladgar and Afifi's SiDES protocol will suffer from the replay attack, forgery attack, Denial-of-Service attack and fail to achieve the forward security. Although Lin's protocol uses timestamp to control the delegation, it does not keep forward security property under the same time frame.

在2007年，Fouladgar和Afifi首先提出了离线式SiDES协定，接著Lin也提出了TCD-RP协定，可让后端伺服器可以授权读取器辨识标签的资讯，但Fouladgar和Afifi的SiDES定理，会遭受重送攻击、伪造攻击、阻断服务攻击以及不具有向前安全性的特性；而Lin的协定虽然使用时戳来做授权的控制，但在相同的时间区段下运作，并不具有向前安全性的特性。

CAN bus has been the most promising fieldbus and it has been widely used in many areas, but with the increasing of complicacy in automation systems for industrial controlling, people have more and more strict requirement to the real-time capability of information, So it is very important to study the real-time characteristic of CAN protocol for surmounting the limitation of aptotic priority in CAN protocol by taking effective measures and improving the real-time characteristic of communication system based on CAN bus.

CAN总线是目前最有前途的现场总线之一，它已经在多个领域得到了广泛的应用，然而随着工业控制自动化系统复杂性的增加，对信息实时性的要求越来越高，因此，研究CAN协议的实时性问题，采取合理的措施克服CAN协议中固定优先级机制的缺陷，提高CAN总线通讯系统的实时性具有重要的应用价值。
