Recently, Huang and Cao proposed a novel and efficient unlinkable secret handshakes scheme with several security features including the affiliation-hiding property and the AKE-security. In this paper, we examine the security of the Huang-Cao scheme and show that the scheme fails to achieve two fundamental security requirements, the affiliation-hiding property and the AKE-security.
