Information Security

In the Department of Computer Science, we have a strong group of faculty and research students working on various topics within information security at large. We aim to develop new solutions for security and privacy in the era of ubiquitous and growing computing and communication infrastructure, by addressing security issues related to several areas of interest, such as cloud computing & big data, networking, software, machine learning and the Internet-of-Things. Our research includes applied cryptographic problems, security protocol design, software & hardware security, trusted networking & computation, secure connectivity, and user authentication.
