摘要

互联网工程任务组(IETF)正在制定ip层加密与认证(IPSEC)标准。我们描述了如何使用“可能的明文”来帮助进行密码分析攻击，并分析协议以显示有多少可能的明文可用。我们还展示了流量分析对密码分析人员的强大帮助。最后，我们概述了一些可能对底层协议进行的更改，这些更改可能会增强它们抵御这些攻击的能力。

Probable plaintext cryptanalysis of the IP security protocols

The Internet Engineering Task Force (IETF) is in the process of adopting standards for IP-layer encryption and authentication (IPSEC). We describe how "probable plaintext" can be used to aid in cryptanalytic attacks, and analyze the protocol to show how much probable plaintext is available. We also show how traffic analysis is a powerful aid to the cryptanalyst. We conclude by outlining some likely changes to the underlying protocols that may strengthen them against these attacks.
