带状态协议标准化的形式化支持

Formal Support for Standardizing Protocols with State

Joshua D. Guttman, Moses D. Liskov, John D. Ramsdell, Paul D. Rowe

摘要:

许多加密协议被设计为仅使用通过开放网络传递的消息来实现其目标。有许多工具都是基于众所周知的基础,用于设计和分析纯粹依赖于消息传递的协议。然而,这些工具遇到的困难时,面对依赖于非本地,可变状态来协调几个本地会话的协议。我们采用这些工具之一,{ \cpsa },以提供自动化的支持推理状态。我们使用瑞安的信封协议作为一个例子来演示如何消息传递推理可以与状态推理相结合,产生有趣的和强大的结果。关键词:协议分析工具,有状态协议,TPM,PKCS#11。

英文摘要:

Many cryptographic protocols are designed to achieve their goals using only messages passed over an open network. Numerous tools, based on well-understood foundations, exist for the design and analysis of protocols that rely purely on message passing. However, these tools encounter difficulties when faced with protocols that rely on non-local, mutable state to coordinate several local sessions. We adapt one of these tools, {\cpsa}, to provide automated support for reasoning about state. We use Ryan's Envelope Protocol as an example to demonstrate how the message-passing reasoning can be integrated with state reasoning to yield interesting and powerful results. Keywords: protocol analysis tools, stateful protocols, TPM, PKCS#11.
