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.

由于互联网用户需要安全而简单的通信工具，保密通信需要密码体制的标准化。然而，没有标准的密码系统，并且在不久的将来创建一个标准系统存在许多障碍。为了解决这些问题，我们提出了“自解密保密通信”。该方法是一种独立于特定密码系统的保密通信方法。发送方不仅向接收方发送密文，还发送其解密算法。对于加密和解密，使用对称密钥密码系统。为此，发送方和接收方必须共同保存密钥，并且应该包含密钥分发机制。在这个项目中，我们提出并实现了一个使用密钥分发中心的密钥分发协议。
