Abstract
Recently, Gu and Xue proposed an improved secret handshakes scheme with unlinkability by modifying the Huang-Cao scheme. Their proposal not only solves security weakness in the Huang-Cao scheme but also is more efficient than previously proposed secret handshakes schemes. In this letter, we examine the correctness of Gu and Xue's security requirements and show that the adversary model is not correctly defined. We also show that the Gu-Xue scheme is not secure against the attacks under correctly defined adversary model.
