An efficient provably secure verifier-based authentication protocol using fractional chaotic maps in telecare medicine information systems

The telecare medicine information systems (TMIS) offer a networking channel across public networks to access remote medical services and enable health care professionals and medical staff to make the best clinical decisions and treatments quickly. The verified-based three-party authentication protocol in TMIS for data exchange, authorizations only two patients/users to accumulation their verifiers in the record of authentication server calculated exhausting own password. The authentication scheme will then verify the verifiers of the patients/users and allow them to exchange electronic medical records securely and easily. In this paper, we provide an effective, provably secure, verified-based three-party authentication protocol for data exchange in TMIS utilising fractional chaotic maps. The authentication protocol provided does not use any public server keys and does not require the number of additional messages and rounds for key validation. The projected protocol is appropriate for TMIS because it has stronger security and cheaper communication costs than the corresponding verified-based approach. The development of smart cities can be accelerated with the proposed protocol.
