Group signature scheme based on verifiable random number
Jun Ye, LI Liu-fen · Journal of Discrete Mathematical Sciences and Cryptography · 2017
With linear equations on finite field, a method to generate verifiable random number is presented. Further, a novel group signature scheme based on that method is designed, which is the first scheme of the application of the verifiable random number on group signature. Member adding and removing can be expediently realized in this scheme. And private keys of members are not needed to be reset in different stages. Finally, comparisons with other schemes related are made to show advantages of ours’.
