Abstract :
Proxy signature can be combined other special signature to obtain some new types of proxy signature. Threshold proxy signature is a variant of the proxy signature. Most of existing threshold proxy signature schemes based on the certificate-based public key systems. But, in some cases, the receiver cannot find out who signed the proxy signatures. In this paper, we put forward to a novel identity-based threshold proxy signature scheme from bilinear pairings without a dealer. Using our scheme, the original signer can know who generated the proxy signature and the receiver can certify the actuality of the group signers. Moreover, the constructions of our scheme would be simpler but still with high security.
