  • Method and system for registering a DRM client
    Patent number: 9184917
    Abstract: A client, method and system for registering a DRM client is disclosed. The method (100) includes the steps of: initiating (110) a registration request via a DRM client with an encrypted registration message including an asymmetric key cryptographic identity, a customer identifier and an application specific information (AINFO) field including a digital signature and a device certificate chain; validating (120) information in the application specific information (AINFO) field by a DRM registration server; and receiving (130) a registration response, the registration response being encrypted and including access information, to obtain content. Advantageously, this method provides an enhanced and reliable means of authentication.
