Abstract:
Systems and methods for enabling data encryption control are described. A requesting entity may request to decrypt an encrypted message. The authorization for the requesting entity to decrypt the encrypted message may be performed by a plurality of controlling authorities. The decryption key for decrypting the encrypted message may be split and encrypted specifically for the plurality of controlling authorities, so that no single controlling authority has enough information to decrypt the encrypted message. A designated number of the controlling authorities may be requested to decrypt an encrypted key part in order for the requesting entity to be authorized to reconstruct the decryption key.
