摘要
为解决数据信息交换过程中的安全问题,在对RSA公开密钥加密算法数学原理进行描述的基础上,给出了利用Solovay-Strassen概率算法生成素数的一种实现方法,用本方法进行的素数测试,可以达到较快的运行速度。讨论了RSA算法在数字电视CAS中的应用,RSA算法会使其加密体制更安全、更有效。
In order to solve the security problem of data message exchange, based on the description of the mathematic principle of RSA public key encryption algorithm, this paper gives a sort of prime number testing method using Solovay-Strassen probability algorithm, by which the prime number created is fast and has no rule, so the security is ensured. This thesis also discusses an application of RSA in conditional access system. When it is used in Digital TV CAS, the encrypt system can be made more safe and efficient.
