Abstract

This paper empirically validates the theoretical frameworks presented in "A Quantum Technology Adoption Framework" [2] and "Why QRNG Confuses PQC" [3]. We conducted a series of file encryption and decryption experiments using NIST-standardized Post-Quantum Cryptography (PQC) algorithms on a defined dataset of PDF and large-scale video files. The performance metrics, including speed and throughput for various KEM and digital signature algorithms (ML-KEM, ML-DSA, Falcon, SPHINCS+) are analyzed.

The results demonstrate the practical feasibility and high performance of deploying PQC,

even for multi-gigabyte files, as an essential and immediate countermeasure against the quantum threat. Furthermore, this paper explores the practical applications of PQC in securing data-at-rest, providing a robust defense against modern threats like ransomware and establishing a "dual-security" paradigm that protects against both classical and quantum adversaries.
