A New Identity-based Proxy Signature Scheme from Bilinear Pairings

A New Identity-based Proxy Signature Scheme from Bilinear Pairings

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 requir...

Zusammenfassung: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
