public key cipher system and RSA public key algorithm
Abstract The paper introduce the idea and character of the Public Key cryptography in a simple way, especially expound the theoretical foundation, the working principle and the concrete realizing procedure of the RSA algorithm. Besides that, it accounts for how the algorithm realize through a simple example. In the end of this article, some weakness which exist up to now are given out with their solution.
