1 Scope
This Part of GB/T 34953 specifies anonymous entity authentication
mechanisms based on signatures using a group public key in which a verifier
verifies a group signature scheme to authenticate the entity with which it is
communicating, without knowing this entity’s identity.
2 Normative references
The following documents are indispensable for the application of this document.
For the dated references, only the editions with the dates indicated are
applicable to this document. For the undated references, the latest edition
(including all the amendments) are applicable to this document.
ISO/IEC 20008-1 Information technology - Security techniques - Anonymous
digital signatures - Part 1.General
3 Terms and definitions
For the purposes of this document, the terms and definitions given in ISO/IEC
20008-1, ISO/IEC 20009-1, and the following apply.
Function that outputs one or more shared secrets, for use as keys, given shared
secrets and other mutually known parameters as input.
4 Symbols and abbreviated terms
For the purposes of this Part, the following symbols and abbreviations apply.
5 Model and requirements
Clause 5 specifies the model and requirements for the anonymous
authentication mechanisms.
6 Key generation process
The key generation process includes key generation algorithms that create the
group membership issuing key, the group membership opening key and the
group signature linking key (or keys) if they are required in the mechanism.
7 Mechanisms without an online TTP
If information contained in the text field of the message-to-be-signed of the
token cannot be recovered from the group signature, then it shall be contained
in the unsigned information of the token.
8 Mechanisms involving an online TTP
Unilateral anonymous authentication means that only one of the two entities is
authenticated and that the identity of the authenticated entity is anonymous to
the other entity.
9 The group membership opening process
This process is optional. The evidence evaluation process is run by an evidence
evaluator, which aims to check whether or not a given signature was created
by a specific signer.
10 The group signature linking process
The linking process is run by a linker for a group, who is allowed to connect
multiple group signatures for the group signed by the same signer.
Annex A
(Normative)
Object identifiers
This annex lists the object identifiers assigned to the anonymous authentication
mechanisms specified in this Part.
Annex B
(Informative)
Information on mechanisms with binding-property
This annex explains the necessity of the binding-property in certain usage
scenarios and also contains guidance on parameter selection.
