Abstract

A new framework is proposed for the analysis of communication protocols that require accountability, such as those for electronic commerce. Informal arguments are presented to show that a heretofore un-explored property "provability" is pertinent to examine the potential use of communication protocols in the context of litigation, and in the context of audit. A set of postulates which are applicable to the analysis of proofs in general (e.g., zero knowledge proofs), and the proofs of accountability in particular, are proposed. The proposed approach is more natural for the analysis of accountability then the existing belief logics that have been used in the past for the analysis of key distribution protocols. Some recently proposed protocols for electronic commerce and public-key delegation are analyzed to illustrate the use of the new analysis framework in detecting (and suggesting remedies for eliminating) their lack of accountability, and in detecting and eliminating redundancies.<>
关于电子商务协议中责任的推理
提出了一种新的框架,用于分析需要问责制的通信协议,例如电子商务协议。提出了非正式的论点,以表明迄今为止尚未探索的属性“可证明性”与审查通信协议在诉讼背景下和审计背景下的潜在用途有关。提出了一组适用于一般证明分析(例如,零知识证明),特别是责任证明的假设。与过去用于分析密钥分发协议的现有信念逻辑相比,所提出的方法更适合于分析问责制。本文分析了最近提出的一些电子商务和公钥授权协议,以说明新的分析框架在检测(并建议消除补救措施)它们缺乏问责性以及检测和消除冗余方面的使用
