Abstract

Selective revocation of software components using a key hierarchy in a content protection system. A content distributor creates a content voucher root key, a content voucher signing key, one or more component root keys, and a content voucher. A component vendor creates a vendor root key, a component class key, a component version key, and an object voucher. The content voucher, object voucher and associated software component for processing content may be communicated to a content user system. The keys are used to sign each other in a novel hierarchical arrangement to provide for determination of integrity and authenticity of software components distributed by the component vendor for use on the content user system. The components may be implicitly authorized by the content distributor for use with selected content as a result of the relationships between the keys in the key hierarchy. Revocation of components may be implemented by inserting a revocation list into the content voucher. The revocation list may be checked prior to allowing access to content. Selective revocation of component versions, classes of components, and component vendors may be supported.
