The digitization of patient health information (PHI) for wireless health monitoring systems (WHMSs) has brought many benefits and challenges for both patients and physicians. However, security, privacy and robustness have remained important challenges for WHMSs. Since the patient's PHI is sensitive and the communication channel, i.e., the Internet, is insecure, it is important to protect them against unauthorized entities, i.e., attackers. Otherwise, failure to do so will not only lead to the compromise of a patient's privacy, but will also put his/her life at risk. This paper proposes a freshness-preserving non-interactive hierarchical key agreement protocol (FNKAP) for WHMSs. The FNKAP is based on the concept of the non-interactive identity-based key agreement for communication efficiency. It achieves patient anonymity between a patient and physician, session key secrecy and resistance against various security attacks, especially including replay attacks.
用于无线健康监测系统（WHMS）的患者健康信息（PHI）数字化给患者和医生都带来了诸多益处和挑战。然而，安全性、隐私性和稳健性仍然是WHMS面临的重要挑战。由于患者的PHI敏感且通信渠道（即互联网）不安全，保护它们免受未经授权的实体（即攻击者）的侵害非常重要。否则，不这样做不仅会导致患者隐私泄露，还会危及他/她的生命。本文提出了一种用于WHMS的保持新鲜度的非交互式分层密钥协商协议（FNKAP）。FNKAP基于非交互式基于身份的密钥协商概念以提高通信效率。它实现了患者与医生之间的患者匿名性、会话密钥保密性以及抵御各种安全攻击的能力，尤其包括重放攻击。
