Abstract
A system and method for secure decryption of an encrypted message, including: by each computer system of a plurality of computer systems, computing a decryption share of the encrypted message using a private share of a secret decryption key; by each computer system, computing a modified decryption share by removing a noise share from the decryption share; and recovering, by one or more of the computer systems, a decryption or plaintext of the encrypted message by aggregating the modified decryption shares without exposing or transmitting the noise shares or noise components between computer systems. In some embodiments, the removal of the noise share may include modular reduction operations, where each computer system masks its respective decryption share to produce a masked share, and where outputs from a plurality of lookup tables are aggregated based on the masked shares using a secure multi-party computation (MPC) protocol.
