Abstract
Various embodiments of a system and method for digital rights management using a secure end-to-end protocol with embedded encryption keys are described. A DRM framework may implement a secure end-to-end protocol configured to protect messages sent between trusted endpoints by encrypting and decrypting the messages within software applications executing on each trusted endpoint. An encryption key embedded within a binary representation of a DRM client may be used by the DRM client to encrypt and decrypt messages sent over the secure protocol. The DRM client may request authentication using the secure protocol and receive an authentication token used by the DRM client to acquire a license to view protected content. The encryption key may be chosen from a pool of encryption keys and embedded in the DRM client during the software build process for the DRM client. The secure protocol may be designed according to Representational State Transfer guidelines.
