Abstract

Security played a significant role in the development of formal methods in the 70s and early 80s. Have the tables turned? Are formal methods now ready to play a significant role in the development of more secure systems? While not a panacea, the answer is yes, formal methods can and should play such a role. In this paper we first review the limits of formal methods. Then after a brief historical excursion, we summarize some recent results on how model checking and theorem proving tools revealed new and known flaws in authentication protocols. Looking to the future we discuss the challenges and opportunities for formal methods in analyzing the security of systems, above and beyond the protocol level.
形式化方法和安全性之间的共生关系
安全在70年代和80年代早期正式方法的发展中发挥了重要作用。形势逆转了吗?正式方法现在是否准备好在开发更安全的系统中发挥重要作用?虽然不是万灵药,但答案是肯定的,正式方法可以而且应该发挥这样的作用。在本文中,我们首先回顾了形式方法的局限性。然后,在简短的历史回顾之后,我们总结了一些关于模型检查和定理证明工具如何揭示身份验证协议中新的和已知的缺陷的最新结果。展望未来,我们将讨论在协议级别之上和之上分析系统安全性的形式化方法所面临的挑战和机遇。
