CCMbAS: A Provably Secure CCM-Based Authentication Scheme for Mobile Internet

To improve the security of authentication system and strengthen privacy protection in mobile Internet environment, this paper proposes a provably secure Chebyshev chaotic map (CCM)-based scheme (CCMbAS). The proposed transformed traditional public key into private combined two keys to compute one-time used encrypt information. is verified using review BAN logic ProVerif simulation tool. verification results confirm that well secured against all existing threats. Compared with similar schemes, more efficient secure. analysis shows can fulfil demands ensure user’s information environment.
