ANSI X9。92-1?2009（R2017）定义了数字签名生成和验证的方法，以保护提供部分消息恢复的消息和数据。本文件是本标准的第1部分，定义了椭圆曲线Pintsov-Vanstone签名（ECPVS）数字签名算法。本标准第2部分定义了有限域Pintsov-Vanstone签名（FFPVS）数字签名算法。ECPVS是一个具有低消息扩展（开销）和可变长度可恢复和可见消息部分的签名方案。ECPVS非常适合于短消息，但其灵活性足以处理任何长度的消息。ECPV应与经批准的哈希函数和经批准的对称加密方案结合使用。此外，本ECPVS标准提供了检查消息冗余的标准。

ANSI X9.92-1?2009 (R2017) defines methods for digital signature generation and verification for the protection of messages and data giving partial message recovery.This document is Part 1 of this Standard, and it defines the Elliptic Curve Pintsov-Vanstone Signature (ECPVS) digital signature algorithm. Part 2 of this Standard defines the Finite Field Pintsov-Vanstone Signature (FFPVS) digital signature algorithm.ECPVS is a signature scheme with low message expansion (overhead) and variable length recoverable and visible message parts. ECPVS is ideally suited for short messages, yet is flexible enough to handle messages of any length.The ECPVS shall be used in conjunction with an Approved hash function and an Approved symmetric encryption scheme. In addition, this ECPVS Standard provides the criteria for checking the message redundancy.
