Abstract

Post-quantum cryptography (PQC) has emerged as a quantum-resilient class of cryptography that will be able to withstand attacks from quantum computers. Among the PQC family, the isogeny-based scheme, i.e., Supersingular Isogeny Key Encapsulation (SIKE) protocol, an alternative candidate in Round 3 of the National Institute of Standards and Technology (NIST), has the advantage of a shorter public-key length. However, longer computational time and larger area overhead are the main constraints for its practical applications. In this brief, we proposed a SIKE accelerator with optimized multiplier and adder designs achieving the lowest area-time (AT) product with high operating frequency. The proposed SIKE accelerator for four different security levels has the highest frequency of 303.0-322.5 MHz with 4.0-21.0% improved AT in comparison to the state-of-the-art designs.
