This paper presents a high speed implementation of a recently developed quantum-safe multivariate polynomial digital signature algorithm on the ARM Cortex-M4 processor. The structure of the algorithm and its different security levels are demonstrated, with a focus on its layered implementation architecture and optimization techniques. The results demonstrate the superior performance of the new algorithm on resources-constrained devices compared to the three standardized NIST PQC digital signature algorithms in terms of processing speed, key and signature size, flash and RAM memory usage. Overall, the performance metrics presented in this study demonstrate the promising potential of that algorithm for securing digital communications in a post-quantum era.
