Abstract

Identity-based (ID-based) public key settings are very good alternatives for the certificate based public key settings. Proxy signatures are good tools to delegate the signing capability by original signer to any other parties. The concept of bilinear pairing is very useful in many signature protocols for the ease of computation. Here, we propose an ID-based multi-proxy multi-signature scheme using bilinear pairing and replacing the certificate generation of Li and Chen scheme [5], by delegation generation. Our scheme is more efficient than the multi-proxy multi-signature scheme given by Li and Chen [5]. Moreover, our scheme satisfies all the security requirements of a proxy signature given in [6].
