Abstract Multi-proxy multi-signature scheme is one of the useful primitives of proxy signature scheme which enables a group of signers to delegate their signing rights to another group of their proxy signers. In literatures, only a few schemes of identity (ID)-based multi-proxy multi-signature (IBMPMS) from bilinear pairings are available but those schemes cannot be considered practical for implementations because either those are insecure or cost inefficient.
