Title
A traceable certificateless threshold proxy signature scheme from bilinear pairings
Abstract
Using our (t, n) threshold proxy signature scheme, the original signer can delegate the power of signing messages to a designated proxy group of n members. Any t or more proxy signers of the group can cooperatively issue a proxy signature on behalf of the original signer, but t-1 or less proxy signers cannot. Recently, in order to eliminate the use of certificates in certified public key cryptography and the key-escrow problem in identity-based cryptography, the notion of certificateless public key cryptography was introduced. In this paper, we present a traceable certificateless threshold proxy signature scheme based on bilinear pairings. For the privacy protection, all proxy signers remain anonymous but can be traceable by KGC through a tag setting. We show the scheme satisfies the security requirements in the random oracle model. To the best of our knowledge, our scheme is the first traceable certificateless threshold proxy signature scheme from bilinear pairings.
