A Scalable Containerised Platform for Benchmarking Classical and PostQuantum Cryptographic Algorithms with Parallel Processing and SNMP Monitoring

The advent of quantum computing necessitates the evaluation of post-quantum cryptographic (PQC) schemes, complementing existing classical mechanisms. This paper introduces a scalable, containerised benchmarking framework for assessing the efficiency of encryption and signature algorithms under both sequential and parallel execution. The system integrates a lightweight web interface, message-driven processing pipeline, and a hybrid execution module supporting parallelisation on either CPU or GPU, with performance data captured via SNMP monitoring. Unlike prior studies, the framework emphasises reproducibility and accessibility by enabling experiments on representative file types and providing a modular “sandbox” for algorithmic evaluation. Experimental results highlight the uniqueness of the solution in supporting heterogeneous parallelisation strategies, offering standardised, fine-grained measurement of computational cost and resource utilisation across both classical and NIST-selected PQC algorithms. The proposed platform contributes a practical and extensible tool for systematic cryptographic benchmarking, guiding future optimisation of secure communication systems in the post-quantum era.
