Security Concerns of Identity Authentication and Context Privacy Preservation in uHealthcare System

Home healthcare based on ubiquitous technology is emerging as a solution to increasing chronic disease patients with the advent of aging of society. While u-healthcare has the advantage that improves accessibility to medical services, it also increases the probability of the infringement of privacy of personal medical information, the leakage of which can do greater damage than any other information. Recently, Huang et al. proposed the identity authentication and context privacy preservation in wireless health monitoring system, which is based on identity-based cryptography and identity-based signature. The purpose of this paper is to review Huang et al.'s security scheme, analyze it focused on the security and privacy concerns, and provide directions to improve the scheme.
