Research on Identification Management Technology for Electric Internet of Things Devices Based on Mixed Cryptographic Mechanism

In order to solve the problem of unified identification, certification and collaborative management for massive electric Internet of Things devices, this paper has studied the security identification management technology, designed the security management system for massive electric Internet of Things devices based on mixed cipher mechanism. It has generated device identification by making device coding rules, selected the corresponding cryptographic algorithm and protocol according to the device type to perform the full lifecycle secure management for massive Internet of Things devices at such links as legitimacy testing, recording and application. The security identification management system has been pilot applied in a provincial electric power company to manage massive of devices. The pilot application results showed that it can realize the unified identification, security management and traceability for electric Internet of Things devices, and met the business application requirements of electric Internet of Things.
