Abstract
The efficient quantum circuit of Post Quantum Cryptography (PQC) impacts both performance and security because Grover’s algorithm, upon which various attacks are based, also requires a circuit. Therefore, the implementation of cryptographic operations in a quantum environment is considered to be one of the main concerns for PQC. Most lattice-based cryptography schemes employ Number Theoretic Transform (NTT). Moreover, NTT can be efficiently implemented using the modulus p= k· 2 m+ 1, called Proth number, and there is a need to elaborate on the quantum circuit for a modular multiplication over p. However, to the best of our knowledge, only quantum circuits for modular multiplication of the general odd modulus have been proposed, and quantum circuits for specific odd modulus are not presented. Thus, this paper addresses this issue and presents a new optimized quantum circuit for Proth Number Modular Multiplication (PNMM) which is faster than Rines et al.’s modular multiplication circuit. According to the evaluation with commonly used modulus parameters for lattice-based cryptography, our circuit requires an approximately 22%–45% less T-depth than that of Rines et al.’s.
