Introduction

In the last few years, tremendous advancements have taken place in the field of quantum computing, which have brought about many changes to the field of cybersecurity, thereby creating both opportunities and challenges related to cybersecurity. The development and advancement of Quantum Cryptography have resulted in cryptographic tools that ensure the protection of data from future quantum-based cyberattacks. Such advancements have facilitated the implementation of Quantum cryptography, quantum-safe communication protocols, and secure computing paradigms to increase the level of security of information. Nonetheless, the current challenges faced by distributed computing systems, in terms of their inability to incorporate Quantum-Resistant Cryptography efficiently and securely, need to be addressed to develop secure computing systems.

Quantum-Resistant Cryptography

Proposed PhD Title 1: Adaptive Post-Quantum Cryptography for Secure Distributed Computing Using Quantum-Safe Encryption

The fast development of quantum computing raises critical concerns about the safety of modern distributed computing environments that use classical public-key cryptography algorithms. As per Baseri et al. (2024), companies need adequate risk assessment frameworks for quantum security to help them move towards quantum-resistant systems. Some recent advancements in Post-Quantum Cryptography, Quantum Encryption, and Distributed Computing have provided some promising solutions to classical cryptographic technologies for securing distributed computing environments. Yet, most of today’s migration plans are concerned with the identification of quantum vulnerabilities and not with the adoption of cryptographically adaptive architectures within heterogeneous Distributed Architectures. With cloud computing, edge computing, and distributed enterprise environments constantly evolving, the necessity for intelligent frameworks capable of dynamic security risk evaluation and automatic deployment of quantum-resistant cryptographic solutions arises.

Problem Statement:
Migration models that are quantum-resistant have been designed to focus on risk assessment rather than incorporating adaptive techniques for using cryptography within diverse SDC infrastructures. These shortcomings make the migration process inefficient, difficult, and reduce cyber resilience against quantum attacks.

Research Gap:

Whereas Baseri et al. (2024) offer a detailed framework for evaluating quantum threats, there is limited literature in terms of the implementation aspect of quantum security. The few works available are not concerned with the adoption of PQC, QSE, and intelligent risk-aware approaches in Secure Computing Architectures.

Research Question:

Can Adaptive Quantum Cryptography enhance the security and robustness of Distributed Architectures against the quantum threat?

Outcome:

The suggested study will come up with an intelligent migration model that will continuously assess the threats from quantum security and will recommend appropriate Quantum Cryptography algorithms and also ensure Quantum Encryption for distributed computing infrastructures.

Proposed PhD Title 2. Cryptographic Agility Frameworks for Post-Quantum Secure Distributed Computing Architectures

The advent of quantum computing is fueling the demand for secure cryptographic techniques that can safeguard distributed digital infrastructures against any future quantum attack. As per Khan et al. (2025), Quantum Cryptography has emerged as an essential part of designing quantum-safe communication networks; however, the effective utilisation of such cryptographic techniques demands the presence of agile cryptographic infrastructures that can cope with the changing security needs. Today’s Distributed Computing Architectures incorporate cloud computing, edge computing, and Internet of Things (IoT). Therefore, these complex environments call for a flexible cryptographic management system. While Quantum Encryption techniques have shown resilience against quantum attackers, there has not been much emphasis on agile cryptographic frameworks that can facilitate smooth algorithmic migration and intelligent key management for seamless operations of Secure Computing.

Problem Statement:
Current distributed architectures utilise a static implementation of cryptography that is hard to migrate to new standards of quantum cryptography as they are created. The inability to do so leaves Secure Computing environments vulnerable to quantum attacks.

Research Gap:
While Khan et al. (2025) stress the significance of cryptographic schemes that are resistant to quantum attacks, they fail to offer any insight into how adaptive cryptography can be used for the purposes of large-scale Distributed Computing Architecture. Current studies have not paid enough attention to the automation of algorithm migration, intelligent key management, and quantum encryption.

Research question:

Does Cryptographic Agility Help Protect Against Secure Computing Architectures in a Post-Quantum Age?

Outcome:

This proposed research would result in the creation of a cryptography agility model that would comprise elements such as Quantum Cryptography, intelligent key management, and Quantum-Safe Encryption. The suggested framework would provide for a seamless movement of algorithms and increase interoperability of the systems, along with offering enhanced cyber resiliency.

Proposed PhD Title 3. Scalable Post-Quantum Cryptography for Blockchain-Based Secure Distributed Computing Architectures

Blockchain has been developed into an essential component of Secure Computing through providing decentralisation and transparency along with immutability in data handling. But the rise of quantum computers poses a threat to the very core of blockchains because quantum attacks can affect cryptographic schemes based on public-key cryptography used for digital signatures and key exchanges. According to Liu et al. (2025), quantum attacks can be harmful to blockchain security, transaction validation, and consensus, so the use of Cryptography is required for protection against such attacks. Though there have been several Quantum Encryption methods proposed for blockchains, their implementation is not without drawbacks, such as added computational load and inefficiency of secure Distributed Computing.

Problem Statement:
Present blockchain protocols suffer from the risk of attacks by quantum computers, and current Cryptography approaches tend to increase computational overhead and decrease system efficiency. This poses difficulties in developing scalable and secure blockchain-based Computing Architectures for supporting future decentralised applications.

Research Gap:
Despite Liu et al. (2025)’s contribution to the discussion on quantum computing’s impact on blockchain technology security, there is a lack of research on optimising Cryptography for a large-scale implementation of Secure Computing using blockchain technology. The current literature does not incorporate Quantum Encryption together with performance optimisation.

Research Question:
Could post-quantum crypto improve PQC security and scalability of B-based SDCA?

Outcome:
The purpose of this research is to create a scalable blockchain architecture using Quantum Cryptography and Quantum Encryption, thereby making secure computing architectures more robust. The proposed architecture will provide better security, consensus efficiency, scalability, and a quantum-resilient computing environment.

Proposed PhD Title 4. Privacy-Preserving Post-Quantum Cryptography for Secure Distributed Computing Architectures

Privacy protection has now become an important consideration in the modern world of  Distributed Computing, where various parties collaborate on processing sensitive data without compromising any confidential information. As per Sharma et al. (2025), Secure Multiparty Computation (SMPC) serves as an appropriate method for collaborative computing, but the current cryptographic techniques are susceptible to future quantum attacks. Thus, the use of Cryptography and Quantum Encryption techniques is necessary in order to secure distributed systems from future computational threats. While various post-quantum cryptographic techniques have already been proposed, their integration within scalable Distributed Computing Architecture, along with efficiency in computation, communication, and privacy, is still a difficult task to accomplish.

Problem Statement:
Although privacy-preserving approaches via the Secure Multiparty Computation paradigm provide good security methods, they are built with traditional cryptography methods, which will be threatened after the emergence of quantum computers. Furthermore, integration of quantum cryptography with these solutions makes them computationally intensive.

Research Gap:
While the study by Sharma et al. (2025) emphasises recent advances in quantum-secure MPCs, there is very little literature available regarding scalable distributed computing architectures that combine quantum cryptography, quantum encryption, and efficient computing.

Research Question:

Does PQC contribute to the enhancement of privacy and scalability in secure computing architecture?

Outcome:
The objective of this research is to formulate a framework for privacy protection through an integration of Quantum Cryptography and Quantum Encryption within the context of Distributed Architectures. It will ensure enhanced confidentiality of information, increased scalability, and security of collaboration.

Proposed PhD Title 5. Hybrid Post-Quantum Cryptography Frameworks for Secure Distributed Computing Architectures

As the development of quantum computing technology proceeds at a breakneck pace, the necessity for reliable cybersecurity strategies to protect blockchain and distributed computing infrastructures from quantum-based attacks has increased. The authors mention that, as of late, Quantum Cryptography has made considerable progress in enhancing blockchain security through implementing quantum cryptography methods, according to Alshammari et al. (2025). However, changing current infrastructure into an entirely quantum-safe system poses numerous challenges related to interoperability, resource usage, and compatibility with the existing infrastructure. Even though Quantum Encryption methods are being constantly developed, their application in various types of Computing Architectures is not widespread yet. In view of the increasing interconnectedness of cloud computing, blockchain technologies, and distributed applications, there is a need for hybrid approaches combining classic and cryptographic methods.

Problem Statement:
The existing blockchain and distributed computing systems depend on classical cryptography or pure quantum cryptography, which results in integration issues. Due to the lack of mixed security architectures, the practical implementation of Quantum Cryptography in Secure Computing cannot be achieved.

Research Gap:                     
While Alshammari et al. (2025) provide a comprehensive analysis of architectures of quantum-resistant blockchain, there is a dearth of literature on the study of hybrid approaches involving the integration of classical cryptographic approaches with Quantum Cryptography and Quantum Encryption. The existing body of literature does not discuss much about interoperability, migration, and security.

Research Question:
How Can Hybrid Quantum Cryptography Schemes Enhance the Security and Interoperability of Computing Architectures?

Outcome:
This study will develop a hybrid framework of security that combines both classical cryptography algorithms and post-quantum and quantum encryption mechanisms to achieve computing architectures. This will help improve the interoperability process and quantum-safe migration of cybersecurity.
