Purpose of event

This seminar will explore the intersection of graph theory, topology, and cybersecurity, highlighting recent advancements in mathematical structures that have potential applications in cryptography and data analysis.

Dr. Ang will present a graph-based cryptosystem that utilizes graphs with large automorphism groups as cipher graphs, aiming to enhance security through structural complexity and symmetry. Dr. A’lawiah will examine self-loop graphs, focusing on their spectral properties and rank to uncover fundamental insights into graph structures. Dr. Fariha will introduce Topological Data Analysis (TDA) and demonstrate how it reveals hidden patterns in high-dimensional data, with applications that range from environmental science to epidemiology.

A research seminar titled “Centre for Cyber Security Seminar: Graph Theory and Data Topology – Innovations in Cybersecurity Research” was held on 25 February 2025, from 2 PM to 5 PM. This seminar focused on exploring the intersection of graph theory, topology, and cybersecurity, highlighting recent advancements in mathematical structures that have potential applications in cryptography and data analysis. The seminar began with a welcome address by Dr. Denis Wong Chee Keong, who introduced the three invited speakers: Dr. Ang Miin Huey, Dr. Noor A’lawiah binti Abd Aziz, and Dr. Nur Fariha Syaqina Mohd Zulkepli, all from the School of Mathematical Sciences at Universiti Sains Malaysia. Prof. Yap Wun She, the Dean of the Faculty, expressed gratitude and presented a souvenir to the three speakers in appreciation for his participation in the event. Dr. Ang Miin Huey kicked off the sharing session with her presentation on “A Graph-Based Cryptosystem Using Graphs with Big Automorphism Group as Ciphergraph.” This was followed by Dr. Noor A’lawiah binti Abd Aziz, who discussed her research on “A Study on the Rank of Self-loop Graphs.” Finally, Dr. Nur Fariha Syaqina Mohd Zulkepli presented on “Exploring the Shape of Data: An Introduction to Topological Data Analysis.”
