摘要
随着电子政务的广泛应用,人们对电子公文的真实性和安全性的要求越来越高,本文提出一种新的电子公文加解密方法,主要基于矩阵的一些组合问题,在加解密过程中减少了使用大量的模指数运算,提高了计算效率,从而提高了电子公文的传输和共享的效率。
With the wide application of e - government, the security and authenticity of electronic documents become more and more important. In this paper, a new encryption and decryption method of electronic document that depends on a kind of matrix combinatorial problem is proposed. The method can reduce the use of a large number of modular exponentiation in the encryption and decryption process, as well as improve the computational efficiency, thereby increase the efficiency of the transmission and sharing of electronic documents .
