AI Technical Summary
Traditional cross-domain authentication methods for IoT devices suffer from centralization and single point of failure issues, and have high computational complexity and certificate management costs, making it difficult to achieve efficient and secure decentralized authentication.
A blockchain-based cross-domain device identity authentication method is adopted. Security parameters are negotiated through a consortium blockchain to achieve distributed key generation and verifiable secret sharing. Registration, update and revocation transactions are designed, and the distributed storage characteristics of blockchain are used for device identity management and cross-domain authentication.
It achieves high efficiency and security in cross-domain device authentication, reduces computational complexity and storage costs, solves the single point of failure and certificate management problems of traditional authentication methods, and improves the security and operational efficiency of cross-domain device authentication.
