Simulation Analysis of SSL3.0 Security Protocol Based on Spi Calculus

安全协议中的错误和漏洞很难完全由人工来发现,借助形式化方法对其进行分析可以保证安全协议的正确性和完整性。目前安全协议的形式化分析和验证已成为网络安全的研究热点,其中基于Sp i演算的模型验证方法是当前的一个重要研究领域。文章介绍了SSL3.0安全协议的握手过程和Sp i演算的基本概念,包括基于Sp i演算认证性的验证方法。在此基础上,基于Sp i演算形式化地建立了SSL3.0安全协议的仿真模型,给出了分析SSL3.0安全协议的详细过程,最终验证了SSL3.0安全协议的认证性。仿真分析的结果表明,Sp i演算能够为安全协议的分析和验证提供可靠和有效的支持。

The error and vulnerability of security protocol hardly can be completely found manually. The analysis based on formal methods can guarantee the rightness and completeness of security protocol. Now the formalized analysis and verification of security protocol has become a research focus of network security, in which the model verification method based on Spi calculus is an important research domain. In the paper, we introduce the handshake process of SSL3.0 security protocol and the basic concept of Spi calculus, including the verification method of authenticity based on Spi calculus. On the basis of this, we formally build the simulation model of SSL3.0 security protocol based on Spi calculus and describe the detailed process of analyzing the SSL3. 0 security protocol. Finally we verify the authenticity of SSL3.0 security protocol. The result of simulation analysis shows that Spi calculus can provide reliable and effective support for the analysis and verification of security protocol.
