Abstract
As an emerging technology, edge computing can solve the problem of limited computing resources of IoT devices under the premise of lower latency. However, the existing mobile edge computing architecture cannot well solve the security problem of the identity authentication of the terminal device. In particular, the cross-domain authentication of the device cannot be completed efficiently when the device is switched between different IoT domains. To address these challenging issues, in this article, a lightweight edge computing cross-domain identity authentication scheme which combines edge computing with blockchain based on master-slave chain is proposed. The scheme uses the consortium blockchain as the master chain, that is, a decentralized authentication platform, realizes cross-domain authentication when the device switches domains, and can also solve the single point of failure problem of traditional authentication. The slave chain is maintained by edge computing nodes and terminal devices in each domain. When devices in the domain are mutually authenticated, the efficiency of authentication can be improved. During authentication, ring signature technology is used to ensure the security of the system, and at the same time, it can effectively save the storage space of the blockchain. Finally, the performance evaluation and security analysis of this scheme have been carried out to prove the safety and effectiveness of our scheme.
