Blockchain-based Internet of Things Traceable and Anonymous Cross-domain AuthenticationScheme
Year: 2025
Type: article
Abstract: With the wide application of Internet of things technology,there is an increasing demand for cross-domain information sharing,and cross-domain authentication scheme is the foundation for ensuring cross-domain secure collaboration.Realizing cross-domain authentication based on the real identity of the device has the risk of privacy leakage,while the anonymous authentication scheme has the hidden danger of making it difficult to track malicious devices.To address the above problems,a traceable and anonymous cross-domain authentication scheme based on blockchain technology is proposed.Combining one-way hash chain and certificateless cryptography,multiple unrelated pseudonym identities and corresponding public-private key pairs are generated for the device.Dynamic accumulator is used to calculate the changed domain information.Different pseudonyms are used for each cross-domain authentication,and identity authentication is performed based on the domain information and the cross-domain credentials issued by the key generation center,which not only protects the privacy of the device,but also recovers the real identity of the malicious device and holds them accountable.BAN Logic Correctness analysis and formal security proofs show that the proposed scheme has high security.Compared with other schemes,the calculation cost and communication cost in authentication process are lower.
