Physical-layer, cryptographic, adversarial, and deployment validation of PLD authentication

Establish physical-layer validation of the modeled recovery asymmetry and missed-active/litter reception, determine mappings from the batch and recovery parameters to Wi-Fi modulation-and-coding or finite-blocklength parameters, and investigate cryptographic origin authentication for Category-127 recovery frames, relay and collusion resistance, real-hardware performance, adaptive attackers beyond channel-independent repeated observations, and implementation of the cross-session retry policy.

Background

The prototype and evaluation use modeled recovery probabilities and a software MAC-level testbed rather than physical wireless measurements or deployed hardware. The authors explicitly leave unresolved the validation of the physical recovery asymmetry, parameterization of the recovery mechanism for Wi-Fi transmission conditions, protection and origin authentication of recovery frames, resistance to relay or collusion attacks, broader adaptive-attacker analysis, real-hardware testing, and implementation of the proposed retry policy.
