摘要： A method enables selected features of a software product residing on an end user electronic device with a license delivered from a licensing provider to a service provider of the end user electronic device. The method includes requesting at least one license to authorize a first service provider. An encrypted installation key uniquely associated with the first service provider is received as well as an authorization agent module for installation on one or more authorization agent devices associated with the first service provider. The encrypted installation key and the authorization agent module are installed on the authorization agent devices. A device-unique identifier (DUID) is generated for each authorization agent device based on hardware characteristics of the respective authorization agent devices. The DUID and the encrypted installation key are sent from the authorization agent device to a licensing provider to obtain the requested license. The requested license is received by the authorization agent devices if the DUID and the encrypted installation key are validated by the licensing provider. The license on authorization agent device authorizes and enables the selected features of the software product on an end user electronic device.

摘要： In one embodiment, a method includes receiving a revocation request for revoking a model type of a device. A first computing device determines a list of device unit identifiers (UIDs) that are associated with the model type from a database. The device UIDs are for devices of the model type manufactured by a first entity. The method adds the list of device UIDs to a device revocation list and outputs the device revocation list to revoke a validity of secure information associated with devices associated with the list of device UIDs.

摘要： A conditional access system (CAS) computer in a downloadable CAS receives a downloadable management certificate (DMC) and determines, using the DMC, security information including a DMC key size and an expiration time of a DMC subordinate certificate authority (sub-CA) certificate, for the client device. The CAS computer then determines whether the DMC is valid based on the expiration time of the DMC sub-CA certificate. If the DMC is determined to be valid, the CAS server sends a cryptographic identity for the client device and a CAS client to the client device protected using the DMC. At a later time, if the DMC key size is considered to be still sufficiently secure, the validity of the DMC is extended by issuing a new DMC sub-CA certificate with the same public key as the original DMC sub-CA certificate.
