基于非正式规格说明的安全协议性能评估

Informal specification-based performance evaluation of security protocols

Bela Genge, Piroska Haller, Iosif Ignat, Ovidiu Ratoi

摘要:

提出了一种安全协议的性能评估方法。基于非正式规范,我们构建了一个规范模型,其中包括,除了协议消息,加密操作的参与者在消息的建设过程中进行。每个密码操作都被分配一个成本,该成本被建模为所处理的消息组件的大小的函数。我们不仅模型的大小经常消息组件,但也产生的各种密码操作的密文的大小。我们说明了我们的方法的适用性,通过比较分析原始CCITT X.509协议和同一协议的稍微修改的版本的性能。

英文摘要:

We propose a performance evaluation method for security protocols. Based on the informal specification, we construct a canonical model which includes, alongside protocol messages, cryptographic operations performed by participants in the process of message construction. Each cryptographic operation is assigned a cost modeled as a function of the size of processed message components. We model not only the size of regular message components but also the size of ciphertext produced by various cryptographic operations. We illustrate the applicability of our method by comparatively analyzing the performance of the original CCITT X.509 protocol and a slightly modified version of the same protocol.
