Semantic Communications Enabled Virtual Reality

This proposed PhD project aims to explore the integration of post-quantum cryptography (PQC) techniques into Semantic Communications Enabled Virtual Reality (SCE-VR) systems to ensure secure and private interactions within immersive environments. By leveraging PQC, which offers cryptographic primitives resilient against quantum attacks, this research endeavours to develop novel cryptographic protocols and mechanisms tailored to the unique requirements of SCE-VR environments. Furthermore, the research will explore the impact of cryptographic overhead on performance and usability, aiming to strike a balance between security and efficiency in SCE-VR systems. Through rigorous analysis, simulation, and experimentation, this PhD project seeks to advance the state-of-the-art in secure communication for immersive virtual reality, paving the way for trusted and resilient semantic interactions in the post-quantum era.

The realm of post-quantum cryptography demands innovative solutions to safeguard information against the looming threat of quantum computers. In this spirit, we propose exploring a promising avenue: utilising non-commutative algebra, such as quaternions, to forge a synergy between isogeny and lattice-based cryptography.

Both isogeny and lattice-based cryptography present compelling advantages for post-quantum security. Isogeny-based cryptosystems offer strong security guarantees and efficient key exchange protocols, while lattice-based schemes boast inherent post-quantum resistance and compact signatures. However, each system faces independent challenges. Isogeny-based schemes struggle with side-channel attacks and complex computations, while lattice-based systems grapple with noise sensitivity and scaling limitations.

My PhD thesis under supervision of Professor Cong Ling aims to capitalise on the unique properties of non-commutative algebras such as quaternions to overcome these individual hurdles and establish a connection between the two cryptographic domains.
One approach would be using quaternions.

Our research strives to achieve the following outcomes:

1. Advance the frontiers of post-quantum cryptography: By establishing a synergistic link between isogeny and lattice-based cryptography through quaternions, we hope to develop more robust and practical post-quantum cryptosystems.
2. Contribute to the thriving field of non-commutative cryptography: Utilising quaternions in this realm sheds light on their potential for cryptographic applications, enriching the field and inspiring further exploration.
3. Expand my own research expertise: Immersing myself in this cutting-edge area will enable me to gain valuable knowledge and experience in advanced cryptography and non-commutative algebra, solidifying my foundation for future research endeavours.
4. Exploring the synergy between isogeny and lattice-based cryptography through the lens of non-commutative algebras holds immense potential for advancing post-quantum cryptography. I am confident that this research, fuelled by my passion for cryptography and mathematical innovation, will yield valuable contributions to this ever-evolving field.
