Improvement Of RSA Algorithm Based On Large Arithmetic Library

With the rapid development of computer technology,network gradually became the dominant platform for people to communicate,people's information is also used to pass through the network,so the network information security has become more and more important.In network communication,the key to the security protection of data transmission is the adoption of safe and efficient password system is an important way to solve the information security.Now in general use for higher level of security industry of the RSA public-key encryption algorithm,but its implementation efficiency problem become bottlenecks in the actual engineering application,therefore,the efficient implementation of RSA encryption algorithm is one of the important research topic in the field of cryptography research.This paper introduces the threat of information security and the current preventive measures,which leads to the introduction of cryptography,and the visual representation of this subject.Next to the basic principle of RSA encryption algorithm and based on mathematical knowledge to carry on the comprehensive introduction,and the research of RSA encryption algorithm and improvement are analyzed and compared,and the research direction of the RSA algorithm and the key points to realize the concise narrative.Finally,the combination algorithm of two encryption algorithms is realized through the study of various methods of improvement,and the software is realized through c + +.
