公开密钥数字签名算法研究

数字签名是密码学中的重要课题之一,它是传统文件手写签名的模拟,能够实现用户对以电子形式存放的消息的验证。当算法公开时,在计算上不可能由加密密钥求解解密密钥,因而可以将加密密钥公开,即公开密钥。RSA密码是一种利用因数分解的困难性而设计的公钥密码。本文详述了RSA加密算法的实现以及如何利用RSA实现数字签名。

Research on digital signatures algorithm of pnblic-key eipher

Digital signatures is one of the important topics in cryptography,it is the traditional hand-written document signed simulation,users can achieve electronically stored information on the certification.When the algorithms open,the decryption key can not be calculated by encryption key so the encryption key could be open,only keep decryption key secret,that is public key.RSA password is a kind of public key cryptography using the difficulties of factor analysis.This paper talked the basic principles of the RSA encryption algorithm and how to achieve digital signatures using RSA in detail.
