Attribute-Based, Usefully Secure Email A Thesis Submitted to the Faculty in partial fulfillment of the requirements for the degree of Doctor of Philosophy in Computer Science by Christopher P. Masone DARTMOUTH COLLEGE Hanover, New Hampshire August, 2008 Examining Committee: (chair) Sean W. Smith, Ph.D. David F. Kotz, Ph.D. Christopher J. Bailey-Kellogg, Ph.D. Denise L. Anthony, Ph.D. M. Angela Sasse, Ph.D. Charles K. Barlowe, PhD Dean of Graduate Studies Abstract A secure system that cannot be used by real users to secure real-world processes is not really secure at all. While many believe that usability and security are diametrically opposed, a growing body of research from the field of Human-Computer Interaction and Security (HCISEC) refutes this assumption. All researchers in this field agree that focusing on aligning usability and security goals can enable the design of systems that will be more secure under actual usage.
