A Lightweight Authentication Scheme in Electric Internet of Things

The traditional authentication mechanism incurred higher computation and communication overhead, which is not applicable for terminal devices directly in Electric Internet of Things because of limited computing and storage resources. We propose a lightweight mutual authentication scheme for the terminal devices in Electric Internet of Things. The scheme combines both symmetric with asymmetric cryptography algorithms, only through two handshakes, which can achieve mutual authentication between the terminal devices, and effectively resist the attacker's replaying, tampering and injection attacking. The analysis demonstrates that the computational and communication overhead is less than those of similar mechanisms, which is opportune for resource-limited terminal in Electric Internet of Things.
