معرفی
Liam Keliher is an Associate Professor in the Department of Mathematics and Computer Science at Mount Allison University. His research focuses on cryptography, particularly cryptanalysis of block ciphers, linear and differential cryptanalysis techniques, and provable security in symmetric-key systems. He has contributed to the analysis of ciphers like Camellia, AES (Rijndael), and SPN structures, emphasizing vulnerability assessment and cryptographic protocol validation.
His work spans theoretical and applied cryptography, including slide attacks on iterated ciphers, weak key identification, and the design of secure substitution-permutation networks. He has published extensively in venues such as the Selected Areas in Cryptography (SAC) workshops and peer-reviewed journals, addressing both classical ciphers (e.g., Hill cipher variants) and modern encryption standards.
Notable contributions include refining bounds for differential and linear cryptanalysis on AES and evaluating security metrics for SPNs with randomized S-boxes. His research bridges foundational cryptographic principles with practical security evaluations, ensuring robustness against emerging threats.
While no scientific awards are explicitly listed, his prolific publication record and conference contributions highlight his expertise in cryptanalysis and cryptographic systems design. He teaches advanced courses in computer science, such as COMP4951-A, and has supervised student projects in related areas.
