摘要
本文研究了有限域矩阵构造技术,对Hill密码体制实施改进,实现了一种具有数字签名功能的Hill密码体制方案,并给出了该方案的详细实现过程。改进后的Hill密码体制具有数字签名功能,能够达到一次一密的效果。
In this paper,we have made improvement to the Hill cryptosystem based on the study of matrix structure method in finite field,then realized an new Hill cryptosystem with the digital signature function.New Hill cryptosystem has the effect of one-time-pad.
