安全协议的知识流分析

Knowledge Flow Analysis for Security Protocols

Emina Torlak, Marten van Dijk, Blaise Gassend, Daniel Jackson, Srinivas Devadas

摘要:

知识流分析提供了一种简单而灵活的方法来发现安全协议中的缺陷。一个协议是由一系列规则来描述的,这些规则约束了知识在主体之间的传播。由于这种特征与协议的非正式描述密切相关,因此它允许简洁和自然的形式化;由于它抽象了消息排序,并统一处理了加密原语的主体和应用程序之间的通信,因此它很容易用标准逻辑表示。在合金建模语言的通用框架,并实例化的两个标准协议,和一个新的密钥管理方案。

英文摘要:

Knowledge flow analysis offers a simple and flexible way to find flaws in security protocols. A protocol is described by a collection of rules constraining the propagation of knowledge amongst principals. Because this characterization corresponds closely to informal descriptions of protocols, it allows a succinct and natural formalization; because it abstracts away message ordering, and handles communications between principals and applications of cryptographic primitives uniformly, it is readily represented in a standard logic. A generic framework in the Alloy modelling language is presented, and instantiated for two standard protocols, and a new key management scheme.
