Abstract

We present a cryptanalysis on the short proxy signature scheme recently proposed in [11] and propose a novel short proxy signature scheme from bilinear pairings. Compared with the existing proxy signature schemes, the signature length of our scheme is the shortest. Our short proxy signature scheme satisfies all the properties required for proxy signatures. We prove that our scheme is secure in the random oracle model.
