Performance Analysis of NIST Round 2 Post-Quantum Cryptography Public-key Encryption and Key-establishment Algorithms on ARMv8 IoT Devices using SUPERCOP

With tens of billions of new IoT devices being utilized, and the advent of quantum computing, our future and our security needs are rapidly changing. While IoT devices have great potential to transform the way we live, they also have a number of serious problems centering on their security capabilities. Quantum computers capable of breaking today’s encryption are just around the corner, and we will need to securely communicate over the internet using the encryption of the future. Post-quantum public-key encryption and key-establishment algorithms may be the answer to address those concerns. This paper used the benchmarking toolkit SUPERCOP to analyze the performance of post-quantum public-key encryption and key-establishment algorithms on IoT devices that are using ARMv8 CPUs. The performance of the NIST round 2 algorithms were found to not be significantly different between the two ARMv8 devices
