【摘要】 结合RSA公钥算法和超混沌加密信号两者的优缺点,提出了一种基于RSA算法和超混沌的复合加密方案。理论分析和仿真结果表明,RSA算法抵抗选择密文攻击、公共模数攻击和低指数攻击的能力得到了提高,同时也不存在混沌加密方法在密钥空间设计上的问题。该方案充分利用了两种加密方法的优点,而克服了各自的缺点,因此其安全性能明显优于单独使用任一加密方法的安全性能。更多还原

【Abstract】 A complex encryption scheme is presented by combining the characteristics of RSA algorithm and that of hyperchaos. Theory analysis and simulation show that the ability of algorithm to counteract chosen-ciphertext attacking, common-module attacking and low exponent attacking is improved; it also avoids the problem of designing for key space of chaotic encryption. The anti-attack ability of this encryption scheme is significantly improved compared to that of the either method, by making full use of advantages and overcoming the disadvantages of two typical encryption methods.更多还原
