    Abstract: "Recently, Hwang and Shi proposed an e cient proxy signature scheme without
    using one-way hash functions. In their scheme, an original signer needn't send a proxy
    certi cate to a proxy signer through secure channels. However, there are two public key
    substitution methods can be used to attack their scheme. In this article, we show that their
    scheme is vulnerable to the public key substitution attacks."
