Abstract :
We present a threshold signature based on non-internative Diffie-Hellman signature. It works in asynchronous communication system and can tolerate Byzantine faults with optimal resilience n ≥ = 3t + 1, where n is the number of the participants and t is the number of the fault participants. The security of this scheme bases on discrete logarithm intractability assumption. We give the security analysis of our proposed threshold signature scheme.
