Abstract
Various embodiments of a system and method for multipronged authentication are described. Embodiments may include a client system that implements a runtime component configured to consume content. The client system may be configured to implement a digital rights management component configured to perform one or more cryptographic operations and also authenticate the runtime component. The client system may receive encrypted content from a remote computer system and receive a given authentication component from a remote computer system; that authentication component may be configured to authenticate the runtime component. The client system may, based on authentication of the runtime component by both the digital rights management component and the given authentication component, decrypt at least a portion of the encrypted content. In this way, the client system may ensure that decryption of the encrypted content may occur only if multiple components authenticate the runtime component, according to some embodiments.
