Abstract
Now the information of the world is developing the security of the information is ing more and more importantly. Digital signature filed will e hot spots in future.
It is the first algorithm for both data encryption and digital can be understood easily by has undergone various tests when it is put as the public key cryptosystem representative approved data integrity is a kind of information technology. It is through the authentication techniques to distinguish true and false. RSA digital signature system using a RSA public key algorithm for digital signature.
The text is about the study of RSA public key encryption,based on this generating RSA digital :
,Firstly on the basis of previous research, a system based on elliptical curve proxy signature, The advantage of public key encryption and the security of RSA digital signature(attack )Secondly,it analyzes the principle of RSA,including how to generat a prime number,how to generat the secret keys and how to encryption as well as decrypt, Thirdly,it states the principle of MD5 in , it states design and realization of RSA digital signature in detail. The main modules includes producing RSA secret keys, implementation of RSA encryption algorithm and decryption algorithm, producing message digest and realizing digital signature and verification by RSA.
Key words: RSA algorithm; encryption; decryption; RSA digital signature
