Patent attributes
This disclosure relates to systems and methods for performing cryptographic operations in connection with the management of electronic content using multiple license services. In some circumstances, a content service may not wish to share unencrypted content keys with a single license service for a variety of security reasons. Embodiments of the disclosed systems and methods may use multi-party cryptographic methods in connection with the management of protected content keys and/or associated licenses and/or the distribution of content keys and/or licenses to authorized users and/or devices. In various embodiments, a content service may split a content key into a plurality of key shares and may transmit the key shares to a plurality of different license services. The license services may coordinate operations to generate a protected content key without revealing unencrypted content key to any of the participating license services.
