Bear: An Open-Source Virtual Secure Coprocessor based on TCPA
Technical Report TR2003-471, Department of Computer Science, Dartmouth College.
August 2003.
Abstract
This paper reports on our ongoing project to use TCPA to transform a desktop Linux machine into a virtual secure coprocessor: more powerful but less secure than higher-end devices. We use TCPA hardware and modified boot loaders to protect fairly static components, such as a trusted kernel; we use an enforcer module---configured as Linux Security Module---to protected more dynamic system components; we use an encrypted loopback filesystem to protect highly dynamic components.
All our code is open source and available under GPL from http://enforcer.sourceforge.net/
