Upgraded network technology presents an advanced technological platform for telecare medicine information systems (TMIS) for patients. However, TMIS generally suffers various attacks since the information being shared through the insecure channel. Recently, many authentication techniques have been proposed relying on the chaotic map. However, many of these designs are not secure against the known attacks. In spite of the fact that some of the constructions attain low computation overhead, they cannot establish an anonymous communication and many of them fail to ensure forward secrecy. In this work, our aim is to present authentication and key agreement protocol for TMIS utilizing a chaotic map to achieve both security and efficiency. The underlying security assumptions are chaotic theory assumptions. This scheme supports forward secrecy and a secure session is established with just two messages of exchange. Moreover, we present a comparative analysis of related authentication techniques.
升级后的网络技术为远程医疗信息系统（TMIS）患者提供了先进的技术平台。然而，由于信息是通过不安全的通道共享的，TMIS 通常会受到各种攻击。最近，许多认证技术已经被提出，依赖于混沌图。然而，其中许多设计并不能抵御已知的攻击。尽管一些构造达到了低计算开销，但它们不能建立匿名通信，而且其中许多构造不能确保前向保密性。在这项工作中，我们的目的是利用混沌图为 TMIS 提出认证和密钥协商协议，以实现安全性和效率。基本的安全假设是混沌理论假设。该方案支持前向保密性，只需两次消息交换即可建立安全会话。此外，我们还对相关认证技术进行了比较分析。
