Quantum-Resistant Cyber Defence in Nation-State Warfare: Mitigating Threats with Post-Quantum Cryptography

Venkat Garikipati, Punitha Palanisamy

Quantum computing, very likely going to be a threat against current cryptographic systems especiallywith respect to war between nations, where secure communication and secured data access are very important.Conventional encrypting schemes such as RSA or ECC depend on mathematical problems that can easily besolved by quantum algorithms, typically Shor's, which makes such schemes vulnerable to attacks in the future.This research investigates how PQC is implemented to combat the looming threats of quantum cyber warfare sothat national security is assured. Among the most powerful PQC candidates are lattice based cryptographictechniques like NTRU Encrypt, Kyber and Dilithium, all representing quantum-resilient security. The researchlooks at the time taken for key generation relative to various security levels and quantum attack detection rates,analyzing in detail how these PQC algorithms stand in protecting military communications and criticalinfrastructure. The inference seems to be that though security levels increase, so does the computational overhead,calling for optimization strategies for realistic deployment. Also, a novel adaptive quantum attack detection systemcan be appended to render threat identification more efficient along the years. The joining of lattice-basedencryption with quantum-resistant cloud storage and secure communication protocols will thus yield a scalableefficient model for post-quantum cyber defense. Above all, the research states the need for quickly changingcryptographic standards to those which afford resistance to quantum attacks to secure sensitive data.

Addressing quantum threats to cryptographic security systems with advanced quantum-resistant algorithms

Sunil Thakur, Lowlesh Yadav, Kanwar Tushar Punj +3 more

The fact that modern cryptographic systems are susceptible to a significant attack from quantum computing which solves complex mathematical problem exponentially faster than the classical scheme of computers makes the present situation a dangerous one. Legacy encryption methods including RSA, ECC, and AES that are the heart of secure communication are especially susceptible to quantum attacks such as Shor’s and Grover’s algorithms. To mitigate this potential threat, this research puts forth state of the art quantum-resistant technologies inclusive of lattice based cryptography and hash based signature solutions. The Lattice-Hash Hybrid method that is proposed, improves security by exploiting the computational intractability of lattice problems and the collision resistance of the hash functions, making it very hard to crack the system using quantum decryption algorithms. In the study, a comparative analysis of the proposed method with traditional lattice-based, hash-based and code-based cryptographic methods is performed. Experimental results suggest that the proposed algorithm features better encryption speed, decreased decryption latency, and increased security level as compared with the current state of the art. The results emphasize the need for the implementation of cutting edge electronic cryptography strategies to protect integrity and confidentiality of data in the days to come within the context of quantum computing. Further research will concentrate on optimizing the proposed techniques further and bringing them to real-world deployment.

Quantum blockchain: Trends, technologies, and future directions

Manjula Gandhi S, Chaitrali Mulay, Karthiganesh Durai +13 more

Abstract Blockchain technology is a highly developed database system that shares information within a business web. It stores details in blocks connected chronologically, ensuring information integrity through consensus mechanisms that prevent unauthorised alterations. This decentralised system removes the need for a believable mediator, mitigating vulnerabilities and enhancing transaction security. Blockchain’s application spans the energy, finance, media, entertainment, and retail sectors. However, classical blockchain faces threats from quantum computing advancements, necessitating the development of quantum blockchain technology. Quantum blockchain, leveraging quantum computation and information theory, offers enhanced security and immutability. In this paper, different mathematical foundations, practical implementations and effectiveness of lattice‐based cryptography in securing blockchain applications are discussed. Analysis of how the cryptographic techniques can protect blockchain systems against quantum attacks is being done by using mathematical formulations and examples. Quantum computing strengthens blockchain security with advanced encryption and authentication, which is critical for safeguarding diverse sectors from evolving cyber threats. Further study on quantum‐resistant design is necessary if blockchain networks are to be robust and intact in the face of future technological developments.
