LLM-Assisted Authentication and Fraud Detection
Emunah S-S. Chan, Aldar C-F. Chan
User authentication and fraud detection face growing challenges as digital systems expand and adversaries adopt increasingly sophisticated tactics. Traditional knowledge-based auth…
Security and Privacy of Wireless Beacon Systems
Aldar C-F. Chan, Raymond M. H. Chung
Bluetooth Low Energy (BLE) beacons have been increasingly used in smart city applications, such as location-based and proximity-based services, to enable Internet of Things to inte…
Toward Safe Integration of Legacy SCADA Systems in the Smart Grid
Aldar C-F. Chan, Jianying Zhou
A SCADA system is a distributed network of cyber-physical devices used for instrumentation and control of critical infrastructures such as an electric power grid. With the emergenc…
A Graph Theoretic Approach for Optimizing Key Pre-distribution in Wireless SensorNetworks
Aldar C-F. Chan
Finding an optimal key assignment (subject to given constraints) for a key predistribution scheme in wireless sensor networks is a difficult task. Hence, most of the practical sche…
Efficient Defence against Misbehaving TCP Receiver DoS Attacks
Aldar C-F. Chan
The congestion control algorithm of TCP relies on correct feedback from the receiver to determine the rate at which packets should be sent into the network. Hence, correct receiver…
On Compression of Cryptographic Keys
Aldar C-F. Chan
Any secured system can be modeled as a capability-based access control system in which each user is given a set of secret keys of the resources he is granted access to. In some lar…
