【摘要】 对公钥和私钥加密算法的典型代表ＲＳＡ和ＤＥＳ算法的数学模型分别进行了研究，并对两种算法的优缺点做了全面的比较分析，在此基础上提出了一种基于ＤＥＳ和ＲＳＡ算法的复用加密方案，为网络环境中的数据安全传输的实现奠定了一定的理论基础．更多还原

【Abstract】 The paper analyzes respectively the mathematic modes of RSA&DES which are typical encryption algorithms for Public and Private Key, the merit and demerit of the algorithms axe compared in full scale. A complex Encryption algorithms based on RSA&DES is put forward to establish an academic foundation for the implement of data Transfer safety in network.更多还原
