(t,n) Threshold Group Signature Scheme Based on the Chinese Remainder Theorem
Yao Jianping · 2008
Nowadays number theory is used widely in public-key cryptography.The idea of public-key cryptography can be used to obtain digital signatures.In most of situations,the signer is generally a single person.However,when the message is on behalf of an organization,a valid message may require the approval or consent of part of people.Threshold signature is an answer to this problem.This paper proposes a threshold signature scheme based on the Chinese Remainder Theorem and Schnorr's signature scheme.
