Implementing CRYSTAL-Dilithium on FRDM-K64
Description
This document presents the performance of the lattice-based signature scheme Dilithium for FRDM-K64 ARM Cortex-M4. Dilithium is a recent post-quantum cryptographic scheme, such as a candidate in the third round of the NIST. The Cortex-M4 is considered a suitable microcontroller for post-quantum cryptography so that FRDM-K64 is used to execute the Dilithium scheme. The PQM4 library and Greconici, Kannwischer, and Sprenkels implementation are compared and improved to achieve a low speed of 17% in NIST Security Level 2.ITESO, A. C.
