摘 要: 信息安全中的加密算法日益受到重视,许多加密算法被提出,其中RSA公钥加密算法有着特殊的作用而被广泛使用。由于混沌序列有着良好的伪随机性和对初始值及系统参数敏感以及遍历性等特点,而具有很好的加密性能。因此根据混沌的这些特点,提出了一种利用混沌系统产生大随机数序列的方法,并把他运用于RSA公钥加密算法中,实验证明该方法是非常有效性的。 The security of encryption algorithm attracts much attention in the information field recently,and many encryption algorithms have been proposed. Include RSA public encryption algorithm and it has been used extensively. Owing to chaotic sequence has several good properties such as pseudo - randomness,and extreme sensitive dependence on initial condition and parameters and so on. So it becomes rich cryptography. In the paper,we study an algorithm which generates a random big number by chaos system,and we implement the method to RSA public encryption algorithm. Finally through experiment demonstrates the proposition is validity,and obtains a good result.
