Abstract: With
the growth of wireless communication technologies and sensor technologies,
ubiquitous Healthcare (uHealthcare) based on Internet of Things (IoT) is becoming a big
research focus from various researchers. However, security and privacy
issues are top most important focuses to be solved for the success of
uHealthcare services. This paper shows that Mahmood et al.’s authentication and
prescription safety protocol is prone to denial of service attack and
stolen-verifier attack. Furthermore, we propose a privacy preserving
authenticated key agreement protocol for IoT based uHealthcare, which is based
on hash function, symmetric key cryptosystem and bilinear pairing. The proposed
protocol efficiently solves the security and privacy problems in Mahmood et
al.’s protocol and also provides computational efficiency compared to the
related protocols.
Keywords: Authenticated
key agreement, authentication, internet of things, prescription safety,
ubiquitous healthcare.
