Latest Patents

Zarchy’s patent, “System and Method for Secure Decryption Using Multi-Party Computation,” describes a way for multiple computer systems to decrypt an encrypted message without exposing or transmitting their noise shares to one another. Each system uses a private share of a secret decryption key to compute a decryption share, then removes a noise share to produce a modified share. The systems aggregate the modified shares to recover the decryption or plaintext.

In some embodiments, the method uses modular reduction and masks each decryption share. Outputs from multiple lookup tables are then aggregated using a secure multi-party computation protocol.
