基于网络的数据安全传输问题是信息安全领域的重要课题之一。分析了对称密码和非对称密码体制的优缺点,介绍了集两者之长的数字签名技术,实现了带有数字签名及验证的数据在网络中加密传输系统的方案设计,利用DES、RSA和HASH函数构建了一种能够实现数据快速加密、并具有数字签名功能的数据加密传输系统,该系统保证了信息的保密性、完整性、身份验证和不可抵赖性。最后,用JAVA语言实现了系统的基本功能。
The issue of network-based data security transmission is one of the important topics in the field of information security. This paper analyzes the advantages and disadvantages of symmetric and asymmetric cryptosystems, introduces the digital signature technology which combines both of them, and realizes the scheme design of encrypted transmission system with digital signature and verification data in the network. Using DES, RSA and HASH function builds a data encryption transmission system that can encrypt data quickly and has digital signature. The system guarantees the confidentiality, integrity, authentication and non-repudiation of information. Finally, using JAVA language to achieve the basic functions of the system.
