Electromagnetic Side-Channel Attack Resilience against PRESENT Lightweight Block Cipher (2022)
Presentation / Conference Contribution
Gunathilake, N. A., Al-Dubai, A., Buchanan, W. J., & Lo, O. (2022). Electromagnetic Side-Channel Attack Resilience against PRESENT Lightweight Block Cipher. In 2022 6th International Conference on Cryptography, Security and Privacy (CSP). https://doi.org

Lightweight cryptography is a novel diversion from conventional cryptography that targets internet-of-things (IoT) platform due to resource constraints. In comparison, it offers smaller cryptographic primitives such as shorter key sizes, block sizes...

Digital vaccination passports are being proposed by various governments internationally. Trust, scalability and security are all key challenges in implementing an online vaccine passport. Initial approaches attempt to solve this problem by using cent... Read More about A Privacy-Preserving Platform for Recording COVID-19 Vaccine Passports.

Electromagnetic Analysis of an Ultra-Lightweight Cipher: PRESENT (2021)
Presentation / Conference Contribution
Gunathilake, N. A., Al-Dubai, A., Buchanan, W. J., & Lo, O. (2021). Electromagnetic Analysis of an Ultra-Lightweight Cipher: PRESENT. In 10th International Conference on Cryptography and Information Security (CRYPIS 2021) (185-205)

Side-channel attacks are an unpredictable risk factor in cryptography. Therefore, continuous observations of physical leakages are essential to minimise vulnerabilities associated with cryptographic functions. Lightweight cryptography is a novel appr...

Correlation Power Analysis on the PRESENT Block Cipher on an Embedded Device (2018)
Presentation / Conference Contribution
Lo, O., Buchanan, W. J., & Carson, D. (2018). Correlation Power Analysis on the PRESENT Block Cipher on an Embedded Device. In ARES 2018 Proceedings of the 13th International Conference on Availability, Reliability and Security. https://doi.org/10.1145/3

Traditional cryptographic techniques have proven to work well on most modern computing devices but they are unsuitable for devices (e.g. IoT devices) where memory, power consumption or processing power is limited. Thus, there has been an increasing a... Read More about Correlation Power Analysis on the PRESENT Block Cipher on an Embedded Device.

Secret shares to protect health records in Cloud-based infrastructures (2016)
Presentation / Conference Contribution
Buchanan, W. J., Ukwandu, E., van Deursen, N., Fan, L., Russell, G., Lo, O., & Thuemmler, C. (2016). Secret shares to protect health records in Cloud-based infrastructures. In 2015 17th International Conference on E-health Networking, Application & Servi

Increasingly health records are stored in cloud-based systems, and often protected by a private key. Unfortunately the loss of this key can cause large-scale data loss. This paper outlines a novel Cloud-based architecture (SECRET) which supports keyl... Read More about Secret shares to protect health records in Cloud-based infrastructures.
