Privacy Preserving Authenticated Key Agreement based on Bilinear Pairing for uHealthcarePrivacy Preserving Authenticated Key Agreement • June 29th, 2021
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.
