Specification of identity format for identity
cryptography application
1 Scope
This document specifies a general identity information identity data structure.
This document is applicable to the application of identity cryptography
technology based on SM2 algorithm and SM9 algorithm. It enables mutual
identification and analysis of identity information between different identification
cryptography technology systems.
2 Normative references
The following referenced documents are indispensable for the application of
this document. For dated references, only the edition cited applies. For undated
references, the latest edition of the referenced document (including any
amendments) applies.

3 Terms and definitions
For the purposes of this document, the terms and definitions defined in GM/T
0044 (all parts) and GM/Z 4001-2013 as well as the followings apply.
3.1 identity
the information that can uniquely identify an entity
NOTE: An identity consists of information that the entity cannot deny, such as the entity’s
identifiable name, email address, ID number, telephone number, street address and so on.
3.2 SM2 algorithm
