Design and Analysis of a Provable Secure Two-Factor Authentication Protocol for Internet of Things

Because sensor nodes are deployed in public areas, these sensors easy to capture by adversaries. Once a is stolen, the sensitive information stored it likely be exposed. Accordingly, designing secure authentication protocol should consider this issue. Sadri et al. recently proposed two-factor with anonymity for wireless networks. Unfortunately, we found that their had design flaw user and phase. Besides, can not resist stolen smart card attacks, impersonation attacks. In addition, does provide perfect forward security. This paper proposes provably overcome weaknesses flaws. By comparing security performance of other related protocols, find our work has reasonable computation overhead better
