Abstract： With the development of the Internet of Things technology and the Internet economy, network security threats and risks under the new technology situation continue to emerge and spread. New application scenarios have caused the blurring of network security boundaries and increased new exposure. Security risks cannot be ignored. Based on zero trust technology, it uses blockchain, device fingerprints, PKI/DPKI, artificial intelligence, lightweight security protocols and algorithms as the identity security infrastructure. The focus is on the design and optimization of identity security infrastructure,IoT gateways,perception gateway node equipment and other identity authentication schemes. Finally, through experiments and analysis, the actual effect of the program is verified.
Key words : zero trust；identity authentication；device fingerprint；blockchain；edge computing
