Our society is increasingly transitioning towards an information-centric paradigm, enabled by pervasive networked computing devices. This has brought concerns about security and privacy to a forefront; attackers can exploit vulnerabilities in our systems and protocols to compromise our critical infrastructure as well as end user devices.
How can we secure our computing systems? How can we protect the privacy of our sensitive information? Princeton EE is in a unique position to counter security and privacy threats, by leveraging our strengths in areas ranging from computer architecture to communication networks to information systems.
We are designing secure computing devices/architectures for mobile devices, medical devices, smart cars, and wearable devices. We are creating secure protocols for communication between devices, including optical, wireless, and Internet communications. We are investigating approaches that protect privacy of user data and communications, with applications to finance, medical records, social networks, and cloud computing. Finally, we are building the mathematical foundations of security and privacy, including information theoretic security and privacy-utility tradeoffs.
