Graphic representing computer security


The Cybersecurity group at OSU develops tools and techniques to protect sensitive data & infrastructure against malicious attacks. We study problems that arise as a result of computation & storage in hostile environments. Our work includes adversarial threat modeling, design of novel protection mechanisms, and analysis of their guarantees.

Our faculty members have specific expertise spanning from foundations of cryptography to network security to cyber-physical and IoT system security. For example, we are actively developing techniques for performing computations (database search, data mining) on information while it remains in encrypted form, strategies to detect & mitigate cyber-attacks on power grids and other infrastructure, and authentication mechanisms for extremely low-power devices.
