Abstract

A proxy signature scheme is a method which allows an original signer to delegate his signing authority to a designated person, called a proxy signer. Up to now, most of proxy signature schemes are based on the discrete logarithm problem. In this paper, we propose a proxy signature scheme and a threshold proxy signature scheme from the Weil pairing, and also provide a security proof.
