An Opportunistic Approach for Cloud Service-Based IoT Routing Framework Administering Data, Transaction, and Identity Security

There has been an asymmetric shift toward harnessing cloud-based technologies as the world focuses on shifting operations remotely. Data security for remote operations is crucial for the protection and preservation of critical infrastructure. Furthermore, there has been an emerging trend to integrate IoT-based devices with the expanding cloud infrastructure. In this work, mobile cloud-based infrastructure is considered where contact opportunities are developed in an opportunistic manner so as to facilitate efficient data forwarding and secure process handling. A probabilistic framework is proposed that facilitates data routing between the nodes and local cloud in an IoT network coupled with a multitier trust and encryption scheme for secure data delivery in the cloud-based IoT network. The proposed scheme is evaluated with simulations over two data sets against attack resilience and routing efficiency-based performance metrics, comparing to standard protocols, such as PRoPHET, MaxProp, ProWait, and TCAFE, which displays the enhancement in operations of Sec-CIoT.
