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...
