Abstract :
Proxy signature schemes allow a proxy signer to generate a proxy signature on behalf of an original signer. In this paper we propose an identity-based proxy signature scheme from bilinear pairings. In comparison with the Xu et al.´s scheme, our scheme is more efficient in computation and requires fewer pairing operations especially in verification phase
