Since the 1990s,a computer network technology makes the further popularization of computer applications and development,which is almost down to human social activity and all areas of life,but how to ensure that information security is a very important issue.According to a variety of security technologies and application requirements,there are many encryption algorithms.The RSA algorithm was acknowledged to be the best one of cryptography in a wide range of application process,the it security and performance continues to be sure,becoming the most popular one of cryptosystems.The RSA algorithm in public-key cryptosystem.
This article first describes the encryption algorithm of the foundations of mathematics,mathematical theory and analysis from the RSA algorithm works.And then discussed the implementation of the RSA algorithm.And then this paper analyzes the RSA security line.Then this paper analyzes the RSA's application status.Including:RSA digital signature application,RSA Data encryption ap
