Embodiment Construction
[0037] In order to make the object, technical solution and advantages of the present invention more clear, the present invention will be further described in detail below in conjunction with the examples. It should be understood that the specific embodiments described here are only used to explain the present invention, not to limit the present invention.
[0038] The invention aims to solve the technical problem that the existing cross-domain authentication system uses a centralized deployment method, which makes the system vulnerable to attacks and data tampering. By combining blockchain technology and using the confidentiality, integrity, and non-tampering characteristics of cryptography, a distributed cross-domain authentication system is realized, which promotes security authentication when accessing between domains of the Internet of Things.
[0039] Such as figure 1 As shown, the blockchain-based IoT cross-domain authentication system includes:
[0040] Network layer...
