Pinpoint: Efficient And Effective Resource Isolation For Mobile Security And Privacy, Paul Ratazzi, Ashok Bommisetti, Nian Ji, Wenliang Du

Electrical Engineering and Computer Science - All Scholarship

Virtualization is frequently used to isolate untrusted processes and control their access to sensitive resources. However, isolation usually carries a price in terms of less resource sharing and reduced inter-process communication. In an open architecture such as Android, this price and its impact on performance, usability, and transparency must be carefully considered. Although previous efforts in developing general-purpose isolation solutions have shown that some of these negative sideeffects can be mitigated, doing so involves overcoming significant design challenges by incorporating numerous additional platform complexities not directly related to improved security. Thus, the general purpose solutions become inefficient and burdensome if …

Privacy In Cooperative Distributed Systems: Modeling And Protection Framework, Afshan Samani

Electronic Thesis and Dissertation Repository

A new form of computation is emerging rapidly with cloud computing, mobile computing, wearable computing and the Internet-of-Things. All can be characterized as a class of “Cooperative Distributed Systems” (CDS) in open environment. A major driver of the growth is the exponential adoption by people and organizations within all aspects of their day-to-day matters. In this context, users’ requirements for privacy protection are becoming essential and complex beyond the traditional approaches. This requires a formal treatment of “privacy” as a fundamental computation concept in CDS paradigm.

The objective is to develop a comprehensive formal model for “privacy” as base …
