Sustainable Quantum-Resistant Security Framework for 6G Military Networks Using Hybrid Post-Quantum Cryptography

Abstract:

(a) Problem Statement/Motivation

The advancement of quantum computing poses a significant threat to conventional cryptographic mechanisms. The classical public-key algorithms such as RSA, Diffie–Hellman, and Elliptic Curve Cryptography (ECC) are vulnerable to the various quantum attacks. The algorithms, such as Shor’s algorithm, compromise the existing encryption schemes.

(b) Solution

To address this issue, long-term secure and sustainable security infrastructures are needed. This paper proposes a Sustainable Quantum-Resistant Security Framework (SQRSF-6G) which is designed for the tactical 6G military networks. It is done by integrating the Hybrid Post-Quantum Cryptography (HPQC) techniques. This framework combines lattice-based cryptography, code-based cryptography, and classical encryption mechanisms. It provides the quantum-resistant authentication, secure key exchange, and confidential data transmission across multiple network layers.

(c) Significant Findings

The statistical performance analysis is performed by comparing the proposed framework with the existing classical cryptographic and standalone PQC approaches. The experimental results indicate that the proposed framework achieves a 35–40% improvement in quantum-attack resilience and a 28% reduction in cryptographic energy consumption. The latency reduced to 22%. These results demonstrate that the proposed approach effectively balances security robustness and sustainability.

(d) Application

The proposed framework focuses on making it suitable for next-generation defence communication systems.
