M-SRS: Secure and Trustworthy Mobile Service Review System Based on Mobile Cloudlet

Service quality management has become a recent phenomenon. Thus, it is necessary for the service consumers to quickly understand the service provided by different vendors through Service Review Systems (SRS). This paper considers the trustworthy SRS of locationbased Service without a trusted review management center in oriented Mobile Social Networks (MSNs). We propose some review statistic modification attacks for service consumers to review a service. For protecting the security and reduce the communication and computation overhead of the SRS, an M-SRS based on Mobile Cloud Computing (MCC) is constructed. Also, to prevent the attacks in existing SRS and guarantee the trustworthiness of the statistic SRS, data entanglement and verifiable service utilization tickets are used. The simulation results show that our scheme could effectively resist the proposed service review attacks, and it is efficient in review submission and review authenticity verification.
