Develop Approaches

Mobile computing technologies are rapidly evolving and phone (and other mobile device) manufacturers are under constant pressure to offer new product models. Each manufacturer customizes operating system software for its devices and often changes this software to support its new models. Given the many manufacturers in the mobile device marketplace and the many different generations of products, there are many customized branches of mobile operating systems in use at any time.

Living in an age when services are often rated, people are increasingly depending on reputation of sellers or products/apps when making purchases online. This puts pressure on people to gain and maintain a high reputation by offering reliable and high-quality services and/or products, which benefits the society at large. Unfortunately, due to extremely high competition in e-commerce or app stores, recently reputation manipulation related services have quickly developed into a sizable business, which is termed Reputation-Escalation-as-a-Service (REaaS).

A wide range of cloud services and applications operate on sensitive data such as business, personal, and governmental information. This renders security and privacy as the most critical concerns in the cloud era. The objective of this project is to question the separation approach in the design of security and reliability features of storage systems, and to investigate new, coding-based security mechanisms based on a joint-design principle. The proposed program will result in a myriad of outcomes.

Database Management Systems (DBMS) have been used to store and process data in organizations for decades. Larger organizations use a variety of databases (commercial, open-source or custom-built) for different departments. However, neither users nor Database Administrators (DBAs) know exactly where the data is stored on the system or how it is processed. Most relational databases store internal data using universal principles that can be inferred and captured.

The Complementary Metal Oxide Semiconductor (CMOS) based security primitives typically suffer from area/power overhead, sensitivity to environmental fluctuations and limited randomness and entropy offered by Silicon substrate. Spintronic circuits can complement the existing CMOS based security and trust infrastructures. This project explores ways to uncover the security specific properties of the magnetic nanowire and capture them in detailed circuit model.
