本文档指定了以下同态加密机制。 -指数ElGamal加密； -佩利尔加密。 对于每种机制，本文件规定了以下流程: -生成相关实体的参数和密钥； -加密数据； -解密加密数据；和 -对加密数据进行同态操作。 附录A定义了分配给本文件中规定的机构的对象标识符。附件B提供了数字示例。

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.
