对基于广义逆矩阵密钥协商协议的优化改进

Optimization and Improvement of Key Agreement Based on Generalized Inverse Matrix

摘要: 基于广义逆矩阵的密钥协商方案在通信领域具有重要的应用价值。近些年随着计算机计算能力的跃升，传统方案的安全性有所下降。本文对传统方案的安全性进行优化，采用在信息传输之前，设置一枚随机密码子的方法，对初始密码矩阵进行加密，使得协议安全性进一步提高。

Abstract: The key negotiation scheme based on generalized inverse matrix has important application value in the field of communication. With the leap in computing power in recent years, the security of traditional schemes has declined. In this paper, the security of the traditional scheme is optimized, and the initial cipher matrix is encrypted by setting a random codon before information transmission, which further improves the security of the protocol.
