随着计算机技术、网络技术的发展,信息的安全性,数据的保密性也迫在眉睫。本文研究了数字签名技术的原理,以VisualC++6.0为开发工具,实现了数字签名的签名和认证,能够对文本生成的数字摘要通过签名算法进行签名,并对签名值利用认证算法进行认证,判断签名的有效性。数字签名可以保证数据的完整性、发送信息的不可否认性和身份的确定性。
With the development of computer technology, network technology, information security, data confidentiality is imminent. In this paper, the principle of digital signature technology is studied. With Visual C ++ 6.0 as the development tool, the digital signature signature and authentication are realized. The digital abstract generated by the text can be signed by the signature algorithm and the signature value is authenticated by the authentication algorithm. Judge the validity of the signature. Digital signatures ensure the integrity of the data, the non-repudiation of the information sent and the certainty of the identity.
