Item The feasibility of memory encryption and authentication(2013-05) Owen, Donald Edward, Jr.; John, Lizy KurianThis thesis presents an analysis of the implementation feasibility of RAM authentication and encryption. Past research as used simulations to establish that it is possible to authenticate and encrypt the contents of RAM with reasonable performance penalties by using clever implementations of tree data structures over the contents of RAM. However, previous work has largely bypassed implementation issues such as power consumption and silicon area required to implement the proposed schemes, leaving implementation details unspecified. This thesis studies the implementation cost of AES-GCM hardware and software solutions for memory authentication and encryption and shows that software solutions are infeasible because they are too costly in terms of performance and power, whereas hardware solutions are more feasible.Item Reliability modeling for capital project decisions(2010-08) Poulassichidis, Antonios; Ambler, Tony; McCann, R. BruceExploration and Production (E&P) project costs within the oil industry are continuously increasing reflecting a reality of more harsh environments, remote locations with minimal existing infrastructure and cost increases for materials and skilled resources. The significant capital expenditures translate to a number of projects either for new or revamped production facilities. Successful project completion requires a series of correct decisions throughout the project life-cycle namely design, construction, operations, maintenance and decommissioning. Using a Reliability, Availability and Maintainability (RAM) model as part of the project decision process is an E&P industry best practice that recently gained acceptance in Hess Corporation. This paper presents the RAM methodology and the gains from its application in a capital project.
