Abstract
There is no valid limited proxy signature scheme which limits signature time and signing times until now.Based on the technique of one-time signature and forward-security signature scheme,we proposed a proxy signature which limits signature time and signing times.This scheme is secure based on difficulties of discrete logarithm and resolving a big number.This scheme satisfies properties of proxy signature.
