The identity (ID) based public key cryptosystem simplifies the key management and provides moderate security with comparison to the certificate based public key cryptosystem. Many signature schemes have been proposed using the identity of user. Proxy signature scheme enables the original signer to delegate his/her signing capability to a proxy signer. Bilinear pairings are useful in signature protocols for the ease of computation. In this paper, we have proposed an ID-based multi-proxy multi-signature scheme from bilinear pairing, using the schemes of Cao and Cao [2, 3] and Li and Chen [7]. We have also discussed the security properties of our scheme.
