Improved, chaotic maps,-based password-authenticated key agreement using smartPassword-Authenticated Key Agreement • November 24th, 2024
Summary: Elaborating on the security of password-based authenticated key agreement, in this paper, the author cryptanalyzes a chaotic maps-based password-authenticated key agreement proposed by C. Guo and C.-C. Chang [Commun. Nonlinear Sci. Numer. Simul. 18, No. 6, 1433–1440 (2013; Zbl 1301.94135)] recently. Specifically, their protocol could not achieve strong user anonymity due to a fixed parameter and a malicious adversary is able to derive the shared session key by manipulating the property of Chebyshev chaotic maps. Additionally, the author also presents an improved scheme to eliminate the above weaknesses and still maintain the efficiency.
