Presentation: Hierarchical Key Agreement over Wireless Health Monitoring Systems
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 and privacy have remained important challenges for WHMSs. Since the PHI is sensitive and the communication channel, i.e., the Internet, is insecure, it is important to protect them against unauthorized entities. Otherwise, failure to do so will not only lead to the compromise of a patient’s privacy, but will also put his (or her) life at risk.
This talk will focus on devising a hierarchical key agreement scheme based on Bilinear Pairing for the security and the privacy of WHMSs. It achieves patient anonymity between a patient and physician, session key secrecy and resistance against various security attacks, especially including replay attacks.
