A 4-tier security framework tailored for Quantumas-a-Service (QaaS) deployments, focusing on securing data-in-transit, demonstrates the viability of modern latticebased cryptography for live environments and provides a structured 3-phase transition roadmap for cloud service providers (CSPs) to achieve quantum-resilience seamlessly.
Abstract
By 2030, an estimated 40% of current cloud infrastructures may be rendered vulnerable by cryptanalytically relevant quantum computers (CRQCs).
This paper introduces a 4-tier security framework tailored for Quantumas-a-Service (QaaS) deployments, focusing on securing data-in-transit. Integrating 3 NIST-standardized post-quantum algorithms (ML-KEM, ML-DSA, and SLHDSA), our architecture mitigates interception threats based on Shor's algorithm.
Emulation across an enterprise cloud topology demonstrates a maximum latency overhead of 17.7 milliseconds per TLS handshake under high-latency WAN conditions, ensuring high-availability operations without catastrophic fragmentation failure.
The proposed model demonstrates the viability of modern latticebased cryptography for live environments and provides a structured 3-phase transition roadmap for cloud service providers (CSPs) to achieve quantum-resilience seamlessly.
This analysis demonstrates that while hybrid PQC-QKD models reduce long-term key compromise probabilities to near 0%, they introduce a 15% to 40% increase in bandwidth overhead during initial cryptographic handshakes during initial cryptographic handshakes.

The advent of quantum computing poses a critical threat to conventional cryptographic systems, potentially rendering many widely used algorithms obsolete. To address this challenge, this study proposes the quantum adaptive security algorithm for key management systems (QASA-KMS), a hybrid security framework that integr...

Legacy smart HVAC controllers rely on vendor-cloud TLS secured by ECDH and RSA, both broken by Shor's algorithm, and typical 10-15 year lifespans mean today's devices remain in service through the quantum-threat era. Direct on-device post-quantum cryptography is infeasible: an ESP32-S3, representative of capable HVAC h...

The emergence of Post-Quantum Cryptography (PQC) Standards necessitates the adoption of quantum-resistant protocols by resource-constrained devices (RCDs). However, the intensive computational overhead and substantial key sizes of PQC render direct localized execution inefficient. This research proposes an edge computi...

The review argues that readiness depends on protocol binding, implementation behavior, monitoring, and governance as much as on algorithm strength, and develops a deployment-readiness framework with four layers: security continuity, protocol integration, operational observability, and crypto-agility.
