Telecare medical information systems (TMIS), with the explosive growth of communication technology and physiological monitoring devices, are applied increasingly to enable and support healthcare delivery services. In order to safeguard patients' privacy and tackle the illegal access, authentication schemes for TMIS have been investigated and designed by many researchers. Many of them are promising for adoption in practice, nevertheless, they still have security flaws. In this paper, we propose a novel remote authentication scheme for TMIS using self-certified public keys, which is formally secure in the ID-mBJM model. Besides, the proposed scheme has better computational efficiency. Compared to the related schemes, our protocol is more practical for telemedicine system.
随着通信技术和生理监测设备的迅猛发展，远程医疗信息系统（TMIS）越来越多地被应用于实现和支持医疗服务。为了保护患者隐私并应对非法访问，许多研究人员对TMIS的认证方案进行了研究和设计。其中许多方案在实践中具有应用前景，然而，它们仍然存在安全缺陷。在本文中，我们提出了一种使用自认证公钥的新型TMIS远程认证方案，该方案在ID-mBJM模型中是形式安全的。此外，所提出的方案具有更高的计算效率。与相关方案相比，我们的协议在远程医疗系统中更具实用性。
