  • Behnam Tonekaboni paper “Noise Decoupling for State Transfer in Continuous Variable Systems” has been accepted to be publish soon at Physical Review A, Phys. Rev. A 109, 032404 – In this study, we have developed a novel protocol aimed at suppressing noise in communication channels. Unlike qubits, which operate on discrete states, optical communication channels utilize continuous variable systems, subject to various types of noise. Inspired by the successful noise-suppressing strategy known as dynamical decoupling in qubits, we have discovered that employing multiple rotation controls can effectively mitigate noise in the channel, leading to the attainment of a high-fidelity final state. Furthermore, we provide numerical examples demonstrating the effectiveness of our protocol, particularly in scenarios where a combination of displacement and squeezing noise is present.

Furthermore, we scrutinize 65 different libraries designed to safeguard both model and data privacy within ML-powered IoT frameworks. This paper presents critical insights and proposes robust solutions aimed at enhancing the security of ML models and data amidst the rapidly evolving landscape of AI and IoT.
  • Erik Buchholz, Sharif Abuadbba, Shuo Wang, Surya Nepal, and Salil S. Kanhere. “SoK: Can Trajectory Generation Combine Privacy and Utility?” accepted at Privacy Enhancing Technologies 2024 (PETS’24) Issue 3. [Data61 target venue; CORE A; Acceptance Rate (AR): 19.5%; Link to PDF]: This paper systematises approaches that target the privacy-preserving publication of location trajectories. Due to the prohibitive privacy-utility trade-off of conventional protection approaches, the release of synthetic data generated through generative deep learning models is considered a promising alternative. In a large-scale experimental study, both state-of-the-art models and generative models for sequential tasks from other domains are evaluated. The results highlight that currently, no solution can combine rigid privacy guarantees and good utility and that generative models from other domains are not readily applicable to trajectory generation. This work exposes a significant gap in the space of trajectory privacy and underlines the need for a generative trajectory model with strong privacy guarantees.

  • Marthie Grobler and Tooba Aamir had a chapter accepted in the book ‘Psybersecurity: Human factors of cyber defence’. The chapter is titled ‘Building cognitive resilience for enhanced cyber governance’. In this chapter, we examine how cybersecurity attacks and events aim to exploit human psychology in the context of governance, as well as explore the triggers that adversaries manipulate to breach security. We discuss how these tactics compromise decision-making processes, data sharing, and citizen engagement, and how this would contribute to the potential erosion of public trust, compromise of sensitive data, and disruptions in governance operations. We further consider to what extent cyber resilience would contribute to one person or entity being more susceptible to cyber incidents than others and explore how cognitive resilience can build a cyber immunity that can be adopted in modern cyber governance frameworks.

Cater, “Satellite-to-Ground Continuous Variable Quantum Key Distribution: The Gaussian and Discrete Modulated Protocols in Low Earth Orbit,” in IEEE Transactions on Communications, doi: 10.1109/TCOMM.2024.3359295. The Gaussian modulated continuous variable quantum key distribution (GM-CVQKD) protocol is known to maximise the mutual information between two parties during quantum key distribution (QKD). An alternative modulation scheme is the discrete modulated CVQKD (DM-CVQKD) protocol. In this paper, we study the Phase Shift Keying (M-PSK) and Quadrature Amplitude Modulation (M QAM) DM-CVQKD protocols along with the GM-CVQKD protocol over a satellite-to-ground link in the low SNR regime. We use a satellite-to-ground link model which takes into account geometric losses, scintillation, and scattering losses from the link distance, atmospheric turbulence, and atmospheric aerosols, respectively. In addition, recent multidimensional (MD) and multilevel coding and multistage decoding (MLC-MSD) reconciliation method models in combination with multiedge-type low-density parity-check (MET-LDPC) code models have been used to determine the reconciliation efficiency. The results show that GM-CVQKD outperforms DM-CVQKD. In addition, GM-CVQKD with MD reconciliation outperforms GM-CVQKD with MLC-MSD reconciliation in the finite size limit by producing positive secret key rates at larger link distances and lower elevation angles.
