Performance Analysis of TLS for Quantum Robust Cryptography on a Constrained Device
This work addresses the need for quantum-resistant security in resource-limited environments, but it is incremental as it focuses on benchmarking existing methods.
The paper tackled the problem of evaluating Post Quantum Cryptography (PQC) algorithms on constrained devices, providing benchmarks of leading algorithms on a low-power single-board device.
Advances in quantum computing make Shor's algorithm for factorising numbers ever more tractable. This threatens the security of any cryptographic system which often relies on the difficulty of factorisation. It also threatens methods based on discrete logarithms, such as with the Diffie-Hellman key exchange method. For a cryptographic system to remain secure against a quantum adversary, we need to build methods based on a hard mathematical problem, which are not susceptible to Shor's algorithm and which create Post Quantum Cryptography (PQC). While high-powered computing devices may be able to run these new methods, we need to investigate how well these methods run on limited powered devices. This paper outlines an evaluation framework for PQC within constrained devices, and contributes to the area by providing benchmarks of the front-running algorithms on a popular single-board low-power device.
