Perception Layer Lightweight Certificateless Authentication Scheme for IoT-Based Emergency Logistics

Emergency logistics is of great significance for supply security in emergencies. As a crucial component of strategic material reserve and allocation, emergency logistics is characterized by high levels of safety and efficacy. The security of the IoT-based emergency logistics system cannot be overstated, considering the potential damage caused by malicious accessors. Authentication is an essential means of system security. Existing certificateless authentication protocols are mostly based on bilinear pairings, which cannot match the objectives of emergency logistics networks for lightweight deployment and fast authentication of massive nodes. In this paper, we propose a lightweight certificateless authentication protocol (CL-LAP) without bilinear pairings. The security is determined by the discrete logarithm problem on elliptic curves. Nonlinear pairings guarantee energy efficiency and minimum computation cost. In addition, we use batch verification to reduce the authentication cost and tackle the problem of quick authentication in broadcast messages. We conduct a security analysis on the proposed CL-LAP under the random oracle model to demonstrate that the proposed scheme can withstand common security threats and provide the necessary security for the perception layer. The performance analysis indicates that the suggested scheme is less complex and more efficient than similar schemes with the same level of security.
