Description

Induced by incorporating the powerful data storage and data processing abilities of cloud computing (CC) as well as ubiquitous data gathering capability of wireless sensor networks(WSNs), CC-WSN integration received a lot of attention fromboth academia and industry. However, authentication as well astrust and reputation calculation and management of cloud serviceproviders (CSPs) and sensor network providers (SNPs) are twovery critical and barely explored issues for this new paradigm.To fill the gap, this paper proposes a novel authenticatedtrust and reputation calculation and management (ATRCM)system for CC-WSN integration. Considering the authenticityof CSP and SNP, the attribute requirement of cloud service user(CSU) and CSP, the cost, trust, and reputation of the serviceof CSP and SNP, the proposed ATRCM system achieves thefollowing three functions: 1) authenticating CSP and SNP to avoidmalicious impersonation attacks; 2) calculating and managingtrust and reputation regarding the service of CSP and SNP;and 3) helping CSU choose desirable CSP and assisting CSPin selecting appropriate SNP. Detailed analysis and design aswell as further functionality evaluation results are presented todemonstrate the effectiveness of ATRCM, followed with systemsecurity analysis.
