Social-Aware Cross-Chain Authentication Strategy in Mobile Edge Computing

With the rapid development of mobile edge computing (MEC), the amount of mobile devices and users is growing rapidly, and the distributed management architecture based on the blockchain technology is gradually used for the demand of trust and privacy protection in MEC. While most of the works focus on how to use blockchain to provide a secure and trusted environment in MEC, the problem of excessive authentication cost caused by repeated authentication has not been solved. This paper proposes a social-aware cross-chain authentication strategy in MEC. The concept of social network is introduced into MEC, based on data collected from the users, we can derive the social connection among users and select notaries from users with high credibility to cross the chain. Simulation results show that the proposed strategy can effectively reduce the system cost of distributed management architecture in MEC.
