保密信息传输的数字签名方案研究

Research of Digital Signature on Secret Information Transmission

结合非对称密码体制和对称密码体制的优点,设计了保密信息传输的基于混合密码算法的数字签名方案,并给出了基于Java Applet技术的详细实现过程。通过对该方案的安全性分析可知,该数字签名方案较好地保证了信息传输的机密性、完整性和不可抵赖性。

The paper provides designs of the digital signature scheme of the security information transmission based on mixed crypto-algorithm according to the merit of the asymmetrical cryptograph and the symmetrical cryptograph. Besides, the paper presents the detailed realization process based on the Java Applet. Through the security analysis of the scheme, this digital signature scheme well guarantees the confidentiality of information transmission, integrity and non-repudiation.
