Abstract

The present invention extends to methods, systems, and computer program products for pre-performing operations for accessing protected content. Cryptographic user key pairs can be pre-generated and distributed in response to a variety of different events prior to provisioning client machine for accessing protected content. Usage licenses can be pre-generated and allocated prior to requests for usage licenses. Usage licenses can be pre-obtained for client machines prior to client machines access protected content. Pre-performed operations can be performed in response to detected events, such as, for example, reduced resource consumption in a Digital Rights Management system.
