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