标准摘要
[中文适用范围]： 本文件规定了基于 ISO/IEC 19592-2 中规定的秘密共享技术的安全多方计算机制的流程。基于秘密共享的安全多方计算可用于机密数据处理。可能的应用示例包括数据保密的协作数据分析或机器学习、隐藏每个投标价格的安全拍卖以及维护私钥保密的加密操作。本文档指定的机制包括但不限于加法、减法、乘以常数、共享随机数生成以及与其参数和属性的乘法。本文档描述了如何使用这些机制和秘密共享技术来执行安全功能评估。 [外文原描述]： This document specifies the processes for secure multiparty computation mechanisms based on the secret sharing techniques which are specified in ISO/IEC 19592-2. Secure multiparty computation based on secret sharing can be used for confidential data processing. Examples of possible applications include collaborative data analytics or machine learning where data are kept secret, secure auctions where each bidding price is hidden, and performing cryptographic operations where the secrecy of the private keys is maintained. This document specifies the mechanisms including but not limited to addition, subtraction, multiplication by a constant, shared random number generation, and multiplication with their parameters and properties. This document describes how to perform a secure function evaluation using these mechanisms and secret sharing techniques.
