Node Switching Method in Power Distribution Internet of Things based on Blockchain

Abstract

With the rapid development of communication and network technology, the Internet of Things for power distribution has become an increasingly important hot topic. Meanwhile, the security at the terminal level of the power distribution Internet of Things is relatively weak. As terminals with different security zones share the same frequency, the adversary may steal the privacy-sensitive information by controlling one of the terminals, particularly in node switching. In this paper, we use block chain and trusted computing technology to realize the secure node switching.
