Secure computation offloading based on social trust in mobile networks

In recent years, the researches on computation offloading have received significant attention. However, due to the long transmission distance, it could increase the network latency and energy consumption. Thus, several researchers proposed the computation offloading in mobile networks. That is, a mobile device could offload a time or energy consuming computation to other nearby mobile devices. However, the security issue in mobile networks becomes more difficult because there is no trust information between any two mobile devices. In this paper, we propose a secure computation offloading approach based on social trust in mobile networks. Moreover, the secure computation offloading based on social trust (SCOST) system is proposed to realize and evaluate the proposed approach.
