00925njm 22002777a 4500 dc Cano Aguilera, Abraham author Rubio García, Carlos author Lawo, Daniel author Imaña Pascual, José Luis author Tafur Monroy, Idelfonso author Vegas Olmos, Juan José author 2024-09-11 The development of quantum computers poses a risk to the cryptographic algorithms utilized by current public key infrastructure (PKI). High performance computing (HPC), inter‐ and intra‐datacenter communications, and governmental communications are particularly vulnerable to security attacks by quantum computers. In response, there are on‐going efforts on implementing post‐quantum cryptography (PQC) despite the considerable overhead involved in processing PQC encrypted data packets in comparison with their classical counterparts. This work aims to help with the transition to quantum resistant cryptographic schemes by means of providing a thorough experimental performance comparison of the four algorithms selected by the National Institute of Standards and Technology (NIST) for standardization when implemented in a data processing unit (DPU). The experiments are conducted at line‐rate, demonstrating for the first time operation at almost 100 Gbit/s and hence suitability for high‐capacity data center environments.
