【摘要】 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。分析了对称密码和公钥密码体制优缺点及其几种通用的密码算法,建立了数据加密传输系统的网络模型,利用DES、RSA和MD5算法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。更多还原

【Abstract】 The safety of data transmission based on the web is an important task in information safety domain. This paper analyses the symmetry code and the excellency or disadvantage of public key code system, introduces a few universal code arithmetic, sets the web model of the data encrypting transmission system. At last, with the DBS, RSA and MD5, a real data encrypting system is set up, which can realize code data, transmit data quickly and have the function of digital signature.更多还原
