Abstract

Quantum computing introduces a fundamental threat to classical cryptographic systems widely deployed in enterprise cloud communication networks. Algorithms such as RSA, ECC, and Diffie–Hellman rely on computational hardness assumptions that can be efficiently broken using quantum algorithms like Shor’s algorithm. This emerging risk necessitates the development of quantum-resistant cryptographic security models capable of ensuring long-term confidentiality, integrity, and authentication in cloud-based systems

This research investigates post-quantum cryptography (PQC) approaches, including lattice-based encryption, hash-based signatures, multivariate polynomial schemes, and code-based cryptography, for securing enterprise cloud communication networks. It further explores hybrid cryptographic architectures that combine classical and quantum-resistant algorithms to support gradual migration in real-world infrastructures.

 The study evaluates secure key exchange protocols, authentication frameworks, and encrypted communication pipelines in distributed cloud environments. Emphasis is placed on scalability, computational efficiency, latency overhead, and resistance to quantum adversaries.

 Findings indicate that lattice-based and hybrid cryptographic models offer the most practical balance between security strength and performance. However, challenges such as increased computational cost, integration complexity, and lack of universal standards remain significant barriers. The study concludes that adopting quantum-resistant cryptographic models is essential for future-proofing enterprise cloud security architectures against the imminent rise of quantum computing threats.
