Making Decryption Accountable [PDF]

, 2017
Decryption is accountable if the users that create ciphertexts can gain information about the circumstances of the decryptions that are later obtained. We describe a protocol that forces decryptors to create such information. The information can’t be discarded or suppressed without detection. The protocol relies on a trusted hardware device.
