This disclosure relates to systems and methods for managing protected electronic content using proxy reencryption techniques. Rights management architectures are described that may, among other things, provide end-to-end protection of content keys from their point of origination at a content creator and/or content service to end user devices. Proxy reencryption techniques consistent with aspects of the disclosed embodiments may enable transformation of a ciphertext under one public key to a ciphertext containing the same plaintext under another public key. Consistent with embodiments disclosed herein, proxy reencryption processes may be implemented using indistinguishability obfuscation and puncturable public-key encryption schemes, functional encryption, and/or white box obfuscation techniques.
