ad-hoc网络中一种新的匿名认证协议

A new authentication protocol for revocable anonymity in ad-hoc networks

Adam Wierzbicki, Aneta Zwierko, Zbigniew Kotulski

摘要:

本文介绍了一种新的协议在ad-hoc网络的认证。该协议的设计是为了满足ad-hoc网络的特殊要求,如节点之间缺乏直接通信或匿名性要求。同时,ad-hoc认证协议必须能够抵抗欺骗、窃听和回放以及中间人攻击。本文分析了现有的基于公钥基础设施的认证方法,发现它们在ad-hoc网络中存在一些不足。因此,提出了一种新的认证协议,基于已建立的密码原语(Merkle的难题和零知识证明)。该协议的研究模型ad-hoc聊天应用程序,提供私人对话。

英文摘要:

This paper describes a new protocol for authentication in ad-hoc networks. The protocol has been designed to meet specialized requirements of ad-hoc networks, such as lack of direct communication between nodes or requirements for revocable anonymity. At the same time, a ad-hoc authentication protocol must be resistant to spoofing, eavesdropping and playback, and man-in-the-middle attacks. The article analyzes existing authentication methods based on the Public Key Infrastructure, and finds that they have several drawbacks in ad-hoc networks. Therefore, a new authentication protocol, basing on established cryptographic primitives (Merkle's puzzles and zero-knowledge proofs) is proposed. The protocol is studied for a model ad-hoc chat application that provides private conversations.
