Abstract

This research addresses the compounded security risks in multi- tenant hybrid cloud environments arising from advanced cyber threats and the emerging capabilities of quantum computing. The study proposes Q-ZAP, a Quantum-Resilient Zero-Trust Anomaly- detection Platform that integrates Post-Quantum Cryptography (PQC) and a Hybrid Quantum-Classical Machine Learning (QML) model within a Zero-Trust Architecture (ZTA). The core component is a Hybrid Autoencoder (HAE) designed for unsupervised anomaly detection in high-dimensional cloud log data. The system employs NIST-standardized PQC algorithms (ML-KEM and ML-DSA) to secure both control and data planes. Experimental results in a simulated environment demonstrate a 13.3% improvement in F1-score over classical baselines, with acceptable overhead from PQC integration.
