Title:
Security Analysis of a Recent Pairing-based Certificateless Authenticated Key Agreement Protocol for Blockchain-based WBANs
Authors: Yong-Jin Kim, Dok-Jun An, Kum-Sok Sin, and Son-Gyong Kim
Abstract:In this paper, we proposed some vulnerabilities of a recent pairing-based certificateless authenticated key agreement protocol for blockchain-based wireless body area networks (WBAN). According to our analysis, this protocol is insecure against key offset attack (KOA), basic impersonation attack (BIA), and man-in-the-middle attack (MMA) of the malicious key generation center (KGC) administrators. We also found and pointed out some errors in the description of the protocol.
