| 摘 要： | We cryptanalyze Kim et al ‘ s onetime proxy signature scheme used in mobile agents, and then a successful forgery is introduced. It is showed that a dishonest customer can successfully forge a vaid onetime proxy signature by impersonating the server. Furthermore, he can request the server with responsibility for the forged bidding information.

| Abstract: | We cryptanalyze Kimet al's one-time proxy signature scheme used in mobile agents, and then a successful forgery is introduced. It is showed that a
dishonest customer can successfully forge a valid one-time proxy signature by impersonating the server. Furthermore, he can
request the server with responsibility for the forged bidding information.
