Multi‐proxy signature is a variant of proxy signature, which allows that a delegator may delegate his signing rights to many proxy signers. Compared with proxy signature, multi‐proxy signature can effectively prevent that some of proxy signers abuse signing rights. In this paper, we propose an efficient multi‐proxy signature scheme in the standard model, which is based on the Waters' signature scheme. Compared with other multi‐proxy signature schemes in the standard model, the proposed scheme further reduces the amount of computations and communications.
