Introduction

Digital signature mechanisms can provide entity authentication, data source authentication, non-repudiation, and data integrity services. The digital signature mechanism satisfies the following requirements. --- If there is only a public verification key, no private signature key, generate a valid signature for any given message in the calculation Is not feasible; --- The signature generated by the signing party cannot be used to generate a valid signature for a new message, nor can it be used to recover a signature. Key --- For signers, finding two different messages with the same signature is computationally infeasible. Most of the signature mechanisms are based on asymmetric cryptography and consist of three basic operations. --- the process of generating a key pair, each key pair including a private signature key and a corresponding public verification key; --- The process of using a private signature key, called the signature generation process; --- The process of using a public verification key is called the signature verification process. There are two types of digital signature mechanisms. --- For a given private signature key, the signer's signature on the same message is the same, this mechanism is called non-random (or indeed () ISO /IEC 14888-1]; --- For each given message and a given private signature key, the signature generated by each signature process is different, this mechanism is called It is random. This section specifies a random digital signature mechanism. Digital signature schemes can also be divided into the following two categories. --- When the entire message needs to be stored and/or transmitted along with the signature, the scheme is called "signature scheme with appendix" [see ISO / IEC 14888]; --- When the whole or part of the message can be recovered from the signature, the scheme is called "signature scheme with message recovery". If the message is short enough, the entire message can be included in the signature and recovered from the signature by the signature verification process; otherwise a part of the message Points can be included in the signature, and the remaining parts are stored or transmitted along with the signature. The mechanisms specified in this section provide complete or partial recovery. The purpose is to reduce storage and transfer management. This section includes five signature schemes. The scheme specified in this section uses a hash function to operate on the entire message. ISO /IEC 10118 specifies a hash function. Some of the schemes specified in this section use a group of elliptic curves over a finite field. ISO /IEC 15946-1.2002 describes the mathematical background and basic techniques for implementing cryptosystems based on elliptic curves over finite fields. Defined in this section The characteristics of the mechanism are given in Appendix G. These mechanisms are related to the mechanisms defined in ISO /IEC 9796-3.2000 and ISO /IEC 15946-4.2004. See Appendix H for correspondence. Information technology security technology with message recovery Digital signature scheme Part 3. Discrete log-based mechanisms

1 Scope

This part of GB/T 15851 specifies five digital signature schemes with message recovery. The security of these programs is based on The difficulty of the discrete logarithm problem of elliptic curves on a finite or finite field. This section also defines an optional control field in the hashing token that enhances the security of the signature. This section specifies a random mechanism. The mechanisms specified in this section are capable of restoring messages in whole or in part. Note. The discrete logarithmic based digital signature scheme with appendix is described in ISO /IEC 14888-3.
