摘要

摘要张和张最近的一篇论文声称，使用代码等价问题的修改版本，构建了第一个基于代码的非交互式密钥交换协议。在本文中，我们解释了为什么这种方法存在缺陷。也就是说，我们描述了一种只涉及线性代数并以压倒性概率完全破坏协议的攻击。一个简单的Magma脚本证实了我们的结果。

An Attack on a Non-Interactive Key Exchange from Code Equivalence

Abstract A recent paper by Zhang and Zhang claims to construct the first code-based non-interactive key exchange protocol, using a modified version of the Code Equivalence Problem. In this paper we explain why this approach is flawed. Namely, we describe an attack which involves only linear algebra and completely breaks the protocol with overwhelming probability. A simple Magma script confirms our results.
