ABSTRACT

A Study of Cryptology

We purchase items at internet shopping mall, transfer money by using internet banking, and trade stocks at cyber stock exchange. Meanwhile, personal information come and go through the internet although it is very crucial and fatal when it is exposed. That is the reason why we need cryptograph which enable us to secure personal information from danger. Therefore development of cryptographic ciphers is a very important in this internet-enabled society. But this is impossible without mathematics indeed. This paper reviews RSA cipher through concrete examples. RSA cipher, a representative public key cipher, is based on numbertheory.
