Abstract

In the past years there has been an increasing interest in developing DRM (Digital Rights Management) systems. The purpose of DRM is to protect the copyrights of content providers and to enable only designated users to access digital contents. From the consumers' point of view, they have a tendency to go against complex and confusing limitations. Consumers want to enjoy contents without hassle and with as few limitations as possible. The concept of Authorized Domain (AD) was presented to remove such problems. However, the previous work on authorized domain has two problems. The first is that it requires a rather expensive revocation mechanism. The second is that the devices still can play contents which are previously obtained even though they are currently out of the authorized domain. On the contrary, our scheme prevents the content from being played by devices which are out of the domain for better security. Furthermore our scheme does not need to maintain a revocation list and can prevent replay attack.
