A Secure and Fast Access Protocol for Collecting Terminal in Power Internet of Things based on Symmetric Cryptographic Algorithm

The development of Power Internet Things has brought a variety access requirements for massive collecting terminals. Based on the characteristics security attributes Things, this paper proposes secure protocol based symmetric cryptographic algorithm large number terminals with limited manufacturing cost, computing power and storage resources. This only uses which fast speed low resource consumption, can realize two-way identity authentication between terminal master station. At same time, combined historical mechanism, it improves efficiency terminals, realizes safe terminal. Finally, compared other protocols, proposed is also effective in performance.
