The main purpose of this paper is to propose a new version of the Diffie–Hellman noncommutative key exchange protocol invented in 2000 by Ko, Lee, Cheon, Han, Kang, and Park. This new version is resistant to linear algebra attacks. It is based on a new complex algorithmic problem using the concept of a marginal set. In particular, it is resistant to attacks by the methods of Cheon and Jun and Tsaban, as well as to attacks by the methods of linear and nonlinear decompositions, developed by the author.

Diffie-Hellman 非交换协议的改进

本文的主要目的是提出 Diffie-Hellman 非交换密钥交换协议的新版本,该协议由 Ko、Lee、Cheon、Han、Kang 和 Park 于 2000 年发明。这个新版本可以抵抗线性代数攻击。它基于使用边缘集概念的新的复杂算法问题。特别是,它可以抵抗 Cheon、Jun 和 Tsaban 方法的攻击,以及作者开发的线性和非线性分解方法的攻击。
