A system includes an electronic circuit that performs operations on encrypted data. The electronic circuit includes electronic circuit elements electrically coupled to receive an encrypted first secret data block including a first data identifier and to decrypt the encrypted first secret data block. The electronic circuit further includes electronic circuit elements electrically coupled to combine the data identifier and an operation identifier of an operation to be executed to generate an intermediate value; apply a one-way hash function to the intermediate value to generate a second data identifier; and encrypt the second data identifier for outputting.

Privacy-enhanced computation via sequestered encryption

A system includes an electronic circuit. The electronic circuit includes a first set of electronic circuit elements electrically coupled to receive first secret data that was encrypted externally to the electronic circuit according to a data key and decrypt the first secret data based in part on parameters included in the data key. The electronic circuit further includes a second set of electronic circuit elements coupled to generate second secret data by executing one or more operations on the first secret data and a third set of electronic circuit elements coupled to encrypt the second secret data based in part on the parameters included in the data key, thereby providing encrypted second secret data for output.
