Efficient design of an authenticated key agreement protocol for dew-assisted IoT systems
2021
Real-time communication is a significant aspect of Internet of Things (IoT). IoT-enabled devices requires the immediate adoption of the highly distributed and heterogeneous framework of collateral merits. Moreover, cloud-based streaming services for IoT have disadvantages such as the inability to provide low latency, mobility support, location-awareness, and real-time data handling, which makes ubiquitous connectivity between the IoT device and server. At the same time, the concept of dew computing modifies the current mechanism of cloud-based services for IoT. It minimizes the response time of comprehensive data, which was collected by nearby resources. However, speedy advancement in IoT directs the evolving security aspects to address emerging challenges. To address the security issues, a mutual authentication architecture has been introduced for dew computing, which ensures secure and authorized session establishment without the requirement of a trusted server. The main objective of the proposed framework is to avoid bottleneck situations without compromising efficiency and security in real-time communication to IoT users through dew computing. To ensure the correctness of protocol, proof of security and simulation using AVISPA are presented. Analysis of performance and comparative study is also conducted to show the advantage in efficiency.
