ID-based threshold signature scheme without random oracles
Bingji Zhao · Computer Engineering and Applications Journal · 2012
Design of threshold signature schemes which are efficient and provably secure in the standard model(without random oracle)is suitable for applications.Based on L-J scheme,the threshold signature scheme is presented and is proved secure in the standard model.The new scheme can tolerate any t less than n/2 + 1 malicious parties,its key generation algorithm doesn't need a trusted dealer and it only runs an interactive algorithm among members.The new scheme proves strong and the adaptive chosen message attack is unforgeable under the computation Diffie-Hellman assumption.
