Scope This document specifies the following mechanisms for homomorphic encryption.-- Exponential ElGamal encryption;-- Paillier encryption. For each mechanism, this document specifies the process for:-- generating parameters and the keys of the involved entities;-- encrypting data;-- decrypting encrypted data; and-- homomorphically operating on encrypted data. Annex A defines the object identifiers assigned to the mechanisms specified in this document. Annex B provides numerical examples.Cross References:ISO/IEC 18033-1ISO/IEC 11770-1ISO/IEC 9797-1ISO/IEC 10116ISO/IEC 18033-4ISO/IEC 18033-5ISO/IEC 18031ISO/IEC 15946-1ISO/IEC 9798-1ISO/IEC 18033-2All current amendments available at time of purchase are included with the purchase of this document.
