基于术语的安全协议合成

Term-based composition of security protocols

Bela Genge, Piroska Haller, Ovidiu Ratoi, Iosif Ignat

摘要:

在安全协议并行组合的上下文中,属于不同协议的消息可以相互交叉,我们引入了一个新的范例:基于术语的组合(即组合的消息组件也称为术语)。首先,我们通过扩展原始串空间来创建协议规范模型。然后,我们提供了一个术语合成算法,根据该算法可以构造新的术语。为了确保安全属性得到维护,我们引入了术语连接的概念来表达术语和加密上下文之间的现有连接。我们说明了建议的组合过程中使用两个现有的协议。

英文摘要:

In the context of security protocol parallel composition, where messages belonging to different protocols can intersect each other, we introduce a new paradigm: term-based composition (i.e. the composition of message components also known as terms). First, we create a protocol specification model by extending the original strand spaces. Then, we provide a term composition algorithm based on which new terms can be constructed. To ensure that security properties are maintained, we introduce the concept of term connections to express the existing connections between terms and encryption contexts. We illustrate the proposed composition process by using two existing protocols.
