An efficient authentication and key agreement protocol for IoT-enabled devices in distributed cloud computing architecture

Abstract With the widespread use of Internet Things and cloud computing in smart cities, various security privacy challenges may be encountered.The most basic problem is authentication between each application, such as participating users, IoT devices, distributed servers, centers, etc. In 2020, Kang et al. improved an protocol for IoT-Enabled devices a environment its main purpose was order to prevent counterfeiting attacks Amin al.’ protocol, which published 2018. However, We found that al.’s still has fatal vulnerability, is, it attacked by offline password guessing, malicious users can easily obtain master key control server. this article, we extend their work design lightweight pseudonym identity based agreement using card. For illustrating our used analysis tools AVISPA Scyther prove defend against existing attacks. will further analyze interaction participants path ensure protection from simulated detailedly. addition, on comparison functions performance, superior other two related protocols. As result, enhanced efficient secure architecture city.
