CA 2532325
A license is issued to a user as decryption and authorization portions. The decryption portion is accessible only by such user and has a decryption key (KD) for decrypting corresponding encrypted digital content and validating information including an identification of a root trust authority. The authorization portion sets forth rights granted in connection with the digital content and conditions that must be satisfied to exercise the rights granted, and has a digital signature that is validated according to the identified root trust authority in the decryption portion. The user issued accesses the decryption portion and employs the validation information therein to validate the digital signature of the authorization portion. If the conditions in the authorization portion so allow, the rights in the authorization portion are exercised by decrypting the encrypted content with the decryption key (KD) from the decryption portion and rendering the decrypted content.
