摘要：
Recently, Sharma et al. (Wirel Pers Commun, 2015. doi: 10.1007/s11277-0152698- 2) proposed a pairing-free certificateless ring signcryption scheme (PF-CLRSC) and used it for the environment of wireless sensor networks. They claimed that their scheme was provably secure. Unfortunately, we present two concrete attacks to demonstrate that their scheme can provide neither confidentiality nor unforgeability against Type I adversary. The analysis shows that Sharma et al.' s PF-CLRSC scheme is not suitable for practical applications.
