Abstract
Aspects of the present disclosure relate to encrypted data processing (EDAP). A processor includes a register file configured to store ciphertext data, an instruction fetch and decode unit configured to fetch and decode instructions, and a functional unit configured to process the stored ciphertext data. The functional unit further includes a decryption module configured to decrypt ciphertext data from the register file to receive cleartext data using an encryption key stored within the functional unit. The functional unit further includes a local buffer configured to store the cleartext data. The functional unit further includes an arithmetic logical unit configured to generate cleartext computation results using the cleartext data The functional unit further includes an encryption module configured to encrypt the cleartext computation results to generate ciphertext computation results for storage back into the register file.
