PRIVACY-ENHANCED COMPUTATION VIA SEQUESTERED ENCRYPTION

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.
