The project develops new technologies for continual, web-scale measurement and rapid defenses against emerging threats to web privacy and security arising from third-party tracking. It draws from the fields of web security, systems, measurement, statistics, and machine learning. The outputs of this project will enable website administrators to find and fix a large class of privacy and security problems. They will help improve existing browser privacy tools.

This research focuses on understanding the digital security and privacy needs of journalists and their sources to evaluate and design communication technologies that better support the fundamental operations of a globally free and unfettered press. Journalists -- along with their organizations and sources -- are known to be high-risk targets for cyberattack. This community can serve as a privacy and security bellwether, motivated to use new technologies, but requiring flexibility and ease-of-use. Many existing secure tools are too cumbersome for journalists to use on a regular basis.

Ensuring a high level of security and reliability in the electronic computing devices is a significant challenge. Central issues include secure and reliable identification, authentication and integrity checking of underlying hardware. Hardware-based security primitives such as physical unclonable functions (PUFs) are still a work-in-progress in terms of the cost they require to guarantee reliable operation and their resistance to physical attacks.

By the end of this decade, it is estimated that Internet of Things (IoT) could connect as many as 50 billion devices. Near Field Communication (NFC) is considered as a key enabler of IoT. Many useful applications are supported by NFC, including contactless payment, identification, authentication, file exchange, and eHealthcare, etc. However, securing NFC between mobile devices faces great challenges mainly because of severe resource constraints on NFC devices, NFC systems deployed without security, and sophisticated adversaries.

The trend of outsourcing semiconductor manufacturing to oversea foundries has introduced several security vulnerabilities -- reverse engineering, malicious circuit insertion, counterfeiting, and intellectual property piracy -- making the semiconductor industry lose billions of dollars. Split manufacturing of integrated circuits reduces vulnerabilities introduced by an untrusted foundry by manufacturing only some of the layers at an untrusted high-end foundry and the remaining layers at a trusted low-end foundry.
