Enabling Quantum-Resistant EDHOC: Design and Performance Evaluation

Blog Article

The Ephemeral Diffie-Hellman over COSE (EDHOC) is a compact and lightweight key establishment protocol for constrained scenarios that provides end-to-end application layer security context.However, because of the vulnerability of the discrete logarithm problem to Shor’s algorithm, a quantum resistant replacement for Diffie-Hellman is required.This paper proposes an architecture to transform EDHOC into a quantum-resistant protocol, with an open-source implementation supporting various Post Quantum Cryptography (PQC) schemes from the National Institute of Standards and Technology (NIST) PQC standardization process.Necessary modifications Ball - Glove Softball Fielding - Senior to EDHOC are analyzed, integrating PQC Key Encapsulation Mechanisms (KEMs) and PQC digital signatures in a complete Post-Quantum (PQ) version of the EDHOC protocol (PQ-EDHOC).PQC operations often involve complex computations and require larger byte sizes, which can challenge resource-constrained devices designed for lightweight operation in constrained network 4 Piece Power Reclining Sofa environments.

To evaluate the applicability of various PQC schemes in a realistic PQ EDHOC environment, various PQC KEM and Digital Signature combinations are assessed for execution time, energy consumption, memory usage, and network performance on an nRF52840 ARM Cortex-M4 platform with a 6LoWPAN (IPv6 over Low-Power Wireless Personal Area Networks) over BLE (Bluetooth LowEnergy) network.Results indicate that NIST standardized ML-KEM emerges as the only suitable KEM choice for resource-constrained environments, while promising new signature schemes, like HAWK, show significant performance improvement over the NIST standardized ML-DSA and selected for standardization FALCON.
