Research Abstract

The standardization of cryptosysems is required for secret communication because internet users need secure but simple communication tools. However, there is no standard cryptosystem and there are many obstacles to creating one standard system in the near future. For the solution of these problems, we proposed "self-deciphering secret communication". This method is a secret communication method which is independent from a particular cryptosystem. A sender sends not only a ciphertext but its deciphering algorithm to the recipient. For enciphering and deciphering, symmetric key cryptosystems are used. For this reason, the sender and the recipient have to keep the secret key commonly, and a key distribution mechanism should be incorporated. In this project, we proposed and implemented a key distribution protocol using key distribution center.
