Abstract

Proxy signature schemes have been suggested for use in a number of applications, so the security of proxy signature scheme is more and more important. However, at present, almost all the proxy signature schemas were proven secure in the random oracle model, which has received a lot of criticism. Recently, Yu et al. proposed a designated verifier proxy signature scheme without random oracles by using Waters hashing technique. The formal models and a strictly logical process were provided in this schema. But Kang et al. Show some attacks on Yu et al.s scheme and offer its insecurity proof. In this paper, in order to overcome the weaknesses in Yu et al.s scheme we make supplements on it and make it secure resist Kang et al.s attacks.
