Abstract:
A digital rights management system includes an authentication module and a decryption module. If desired, the modules can be implemented in separate integrated circuits. The authentication module retrieves authentication information for protected content and powers down after the authentication information is retrieved. The decryption module decrypts the protected content based on the authentication information while the authentication module is powered down.
