Abstract
The paper discusses the correctness of Lee, Hwang and Wang’s comments on on Zhang’s proxy signature schemes. In particular, it is shown that the cheating attack proposed by Lee, Hwang and Wang can be detected by the owner of the signature scheme. It is argued that considering the context in which proxy signatures are used, the attack is not a security problem. The work is concluded by a discussion about the non-repudiation controversy incorrectly observed by Lee, Hwang and Wang.
