ID-Based Threshold Proxy Signature Scheme from Bilinear Pairings

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.

ID-based signature schemes from bilinear pairing: A survey

“…We have discussed an ID-based threshold ring signature scheme [48] in the section of ID-based ring signature. Recently, Lu et al [67] proposed an ID-based (t, n) threshold proxy signature scheme from bilinear pairings, with the facility of revocation of the identity of the proxy signer. Signature construction in their scheme is based on the scheme of Lu et al [68].…”
