Dynamic group key management for efficient fog computing

Abstract

Cloud system is a new computing technology for dealing with IT services at the Internet server system. In spite of its advantages in various aspects, it is not proper for IoT (Internet of Things) services that require high density and real time data processing. Fog computing is a new paradigm appropriate for decreasing data processing latency, managing the mobility, and increasing the service efficiency of IoT. However, there is a lot of security vulnerabilities for fog computing because of the lack of security related systems. In this work, we propose a group key management for the secure fog computing which can be adjusted dynamically based on the mobility of the IoT devices. Our proposed system can increase the system efficiency by controlling the IoT groups and the group keys management. © Springer International Publishing AG, part of Springer Nature 2019.
