  Abstract

Nowadays, it is considered as an important task to protect digital contents from illegal use and reproduction. In many cases, there are secure servers to authenticate the allowed users and the user authentication process is performed by communication between the servers and users. However, if the number of users and contents are increased, the servers should treat a large amount of authentication loads and the authentication cost will be considerably increased. Moreover, this scheme is not adequate for some players in which only a limited function of communication is deployed. In order to solve this problem, this paper proposes an authentication method which can certificate both the digital contents and players, and prevent illegal reproduction without the certification server. The proposed scheme is secure in the replay attack, the man in the middle attack, and data substitution attack.
