Abstract— 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.
