A threshold group signature scheme based on RSA and discrete logarithm
Wei Ren-yong · Information technology newsletter · 2004
This paper proposes a new (t,n)threshold signature scheme with high security and good property based on factoring of RSA and discrete logarithm. The security of the proposed threshold signature is based on the difficulty of computing the discrete logarithm modulo for a composite number and the factorization problem of large integer. The advantage our of the scheme is not only satisfied with traceability and avoiding the conspiracy, but also satisfied with the verification simply with a little time of computing, anonymity, withstanding the forgery attack and stableness.
