Information technology is an established component of the infrastructure of modern societies, and cryptography is a cornerstone of information security. Provable security quantifies the resilience of cryptographic constructions to attacks. This quantification is often relative to the hardness of a handful of reference "intractable" problems like integer factorization. Because of the intrinsic strength of heterogeneity, diversifying the set of intractable problems enhances the robustness of the overall structure.

The last decade has seen the tremendous growth of the so-called Social Web and this trend is expected to continue in the years to come. As the distinction between the Web and the Social Web disappears, more and more people turn to them daily for information related to important medical, financial and political decisions. Therefore, there is an indisputable need for reliable information in the online world.

Current information technology enables many organizations to collect, store, and use massive amount and various types of information about individuals. Governments and other organizations increasingly recognize the critical value and enormous opportunities in sharing such a wealth of information. However data privacy has been a major barrier for such information sharing, bringing much attention to privacy preserving data publishing and analysis techniques. Differential privacy is widely accepted as one of the strongest unconditional privacy guarantees.

Recent cyber attacks have shown the degree of vulnerability on the individual to the corporate to national level. Everyone is vulnerable, from the consumer using a credit card to make an online purchase, to the multi-national corporation whose systems are hacked, to national infrastructure and defense networks.

Towards enhancing trustworthiness of wireless integrated circuits, this project investigates the problem of hardware Trojans in the analog/RF domain. Hardware Trojans are maliciously-intended modifications to fabricated integrated circuits, making them capable of additional functionality which is unknown to the designer and user, but which can be exploited by the perpetrator after chip deployment to sabotage or incapacitate it, or to steal sensitive information.
