Enabling Fog Complex Security Services in Mobile Cloud Environments

Abstract

The security infrastructure in modern mobile cloud relays on a set of atomic security services like key distribution, and authentication services which are mostly deployed at the fog. A mobile node may provide a simple or an atomic security service. Complex security services are obtained by coordinating several atomic services at different nodes. In mobile fog environments, the availability of such services for the mobile nodes at the edge straggles challenging nature of the environment and then service availability is deeply affected. Complex security requirements require available several atomic services at the edge and fog levels. So, increasing atomic service availability is vital and enhances security features between the fog and the edge. In this work a proactive complex security service replication protocol for increasing availability of fog security services is proposed. The protocol is able to manage proactively replicas whenever they are requested. It is aware of the distributed resources at the edge nodes. Using an extensive simulation analysis, the protocol performance shows a better achieved availability and reasonable response time for complex security services in different configurations.
