Enhancing Data Confidentiality in Wireless Sensor Networks Using Hybrid Encryption and Dynamic Key Management

Distributed Denial of Service (DDoS) attacks and unauthorized data accesses are some of the major problems encountered in Wireless Sensor Networks (WSNs) primarily due to the limitations in computation and energy of the sensor nodes. Typical single-algorithm cryptographic solutions fail to meet security strength versus...

Trust-aware hybrid QKD–PQC key management for quantum-safe communication networks

This paper presents a dual-layer, trust-aware key-management framework that uses BB84 QKD as the primary channel and a Ring-LWE/Kyber key-encapsulation mechanism as a quantum-safe fallback, governed by a controller monitoring the quantum bit-error rate (QBER) and a trust signal.
