METHOD FOR COMMUNICATING DATA

摘要

A method for communicating data is provided to simplify an authentication process and guarantee secure data transfer between a domain manager and a domain client forming a domain which is a basic unit of a DRM trusted framework. A domain client registered to the domain generates an encryption key including authentication information of the domain client(S2). Transmission data is encrypted by using the encryption key and the encrypted transmission data is transmitted to the domain manager(S3). The authentication information includes at least one of a domain representative token issued from a domain representative of the domain and an ID of the domain client. The transmission data is connection request data for requesting connection to the domain manager.
