- Abstract
- There are considered group signature protocols of new types: collective signature for group signers and collective signature for group signers and individual signers. Implementations of new-type protocols, which are based on computationally difficult problems of finding discrete logarithm and finding roots modulo a large prime number having special structure. It is shown possibility to implement protocols of the proposed types with using the signature generation and signature verification procedures specified by Russian standard GOST R 34.10-2012.
