Abstract:
The rapid development of the industrial internet of things （IIoT） has brought huge benefits to factories equipped with IIoT technology， each of which represents an IIoT domain. More and more domains are choosing to cooperate with each other to produce better products for greater profits. Therefore， in order to protect the security and privacy of IIoT devices in cross-domain communication， lots of cross-domain authentication schemes have been proposed. However， most schemes expose the domain to which the IIoT device belongs， or introduce a single point of failure in multi-domain cooperation， thus introducing unpredictable risks to each domain. We propose a more secure and efficient domain-level anonymous cross-domain authentication （DLCA） scheme based on alliance blockchain. The proposed scheme uses group signatures with decentralized tracing technology to provide domain-level anonymity to each IIoT device and allow the public to trace the real identity of the malicious pseudonym. In addition， DLCA takes into account the limited resource characteristics of IIoT devices to design an efficient cross-domain authentication protocol. Security analysis and performance evaluation show that the proposed scheme can be effectively used in the cross-domain authentication scenario of industrial internet of things.
