METHOD AND SYSTEM FOR STORING A KEY IN A REMOTE SECURITY MODULE

摘要

The invention concerns a method for obtaining assurance that a content control key is securely stored in a remote security module for further secure communications between a content provider and said security. A security module manufacturer, which has a pre-established trustful relation with the security module, imports a symmetric transport key into the security module, wherein the symmetric transport key is unique to the security module. The content provider shares the symmetric transport key with the security module manufacturer and exchanges messages with the security module through a security module communication manager in order to get the proof that the security module stores the content control key. At least a portion of the messages exchanged between the content provider and the security module are protected using the symmetric transport key.
