With the advent of 5G technologies, there has been a tremendous usage of wireless sensor network (WSN) devices around different fields of applications. As a result, huge Volume of different Variety and Varacity of data are generated/gathered from these wireless sensor devices at high Velocity; thereby, classifying this data as Big data. To store and process the big data generated by the sensor devices, the researchers (from the academic and industry world) proposed usage of the fog computing (FC) for easy handling of the data using the fog nodes.
Even though, the data are stored on the fog nodes, one of the extremely critical and hardly explored issues includes the verification of the fog service providers (FSPs) with the sensor network suppliers (SNPs). This verification includes the trust, the reputation, and the auditability of organizations involved in the FSPs and the SNPs. To overcome this limitation, we propose a third-party auditor (TPA) based novel authenticated trust and reputation calculation and management (ATRCM) framework for FC-WSN grouping and integration. Between the FSP and the SNP, the TPA acts as a verification authority to verify and trust the data stored (or received) on the fog node from the SNP. One party request the TPA for their trust verification with other party and then TPA verify data. The proposed ATRCM framework accomplishes the three functions:
1) Verifying CSP and SNP to stay away from malicious impression attacks;
2) Computing and managing trust and reputation with respect to the service of CSP and SNP
3) Helping the fog service user (FSU) to choose appropriate FSP and support the FSP in selecting suitable SNP. Complete analysis and design as well as further functionality assessment result are accessible to display the efficiency of ATRCM, follow with system safety analysis
