OPAQUE-IoT: an optimization-driven PUF-Blockchain authenticated key agreement protocol with adaptive resource management for constrained IoT networks
OPAQUE-IoT, an Optimization-driven PUF-Blockchain AKA Protocol for constrained IoT networks integrates PUF-based hardware identity verification, a permissioned blockchain for decentralized trust management, and the Adaptive Security-Energy Trade-off Optimizer (ASETO), which jointly minimizes authentication latency and energy consumption under formal security constraints.
