To solve security and privacy issues in wireless body area networks, several types of digital signature schemes have been adapted to a number of authentication protocols. Recently in IEEE TRANSACTIONS ON INFORMATION FORENSICS AND SECURITY (TIFS) (DOI: 10.1109/TIFS.2015.2414399), Xiong and Qin proposed a revocable certificateless encryption (R-CLE) scheme against decryption key exposure, and a revocable certificateless signature (R-CLS) scheme against signing key exposure. Then they proposed a revocable and scalable certificateless remote authentication protocol with anonymity for wireless body area networks based on the combination of R-CLE scheme and R-CLS scheme. However, we show that their RCLS scheme is insecure against type I adversaries: a type I adversary who knows only a user's secret value can forge signatures on any messages in the same time period. Hence, their authentication protocol fails to meet the claimed security requirements.
