Abstract

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.
