  • Publication number: 20240204990
    Abstract: The disclosure relates to, among other things, systems and methods for facilitating the secure recording of assertions made by entities tied to identities. Embodiments of the disclosed systems and methods may allow users to make non-revocable, difficult to forge, cryptographic assertions tied to their identities through the posting of entries in an immutable ledger. In certain embodiments, a user's cryptographic assertions may be preceded by ledger entries which feature certificates from trusted authorities that tie the keys used for making assertions to the user's identity. Further embodiments provide for a mechanism for disabling further entries posted under a user's key, either automatically or at the user's initiation.

  • Patent number: 11985237
    Abstract: This disclosure relates to, among other things, systems and methods for deriving key identifiers and managing mapping between keys and key identifiers. Consistent with embodiments disclosed herein, the disclosed systems and methods may provide a mechanism that allows multiple parties to reconstruct unique identifiers given a set of known inputs that may be used to look up, identify, and/or otherwise access services and/or data objects. In some embodiments, this may allow for a service provider and a rights management service to independently derive key identification information based on information that both entities share (e.g., a content document such as a Content Protection Information Exchange Format document), thereby reducing requirements to maintain such mappings.

  • Publication number: 20240080188
    Abstract: This disclosure relates to, among other things, key generation systems and methods. Certain embodiments disclosed herein provide for generation of cryptographic keys based on one or more defined key generation rules. Key generation consistent with various aspects of the disclosed embodiments may increase the difficultly and/or cost of producing public keys and, by extension, discourage the generation of fake keys used in connection with a key flooding attack. In certain embodiments, generated keys and/or associated key generation rules may depend, at least in part, on associated binding data.

  • Publication number: 20240063999
    Abstract: 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.
