Abstract

This chapter describes moats and drawbridges (Huffmire et al., Proceedings of the 2007 IEEE Symposium on Security and Privacy, Oakland, CA, USA, May 2007), a method for separating multiple cores on a single reconfigurable chip. Moats provide logical isolation by placing cores into distinct areas of the chip in a verifiable manner. Drawbridges use interconnect tracing to statically verify that only legal connections between system elements are allowed and that interfaces carrying sensitive data have not been tapped or routed to other cores or I/O pads. To facilitate legal communication between cores, two alternative communication architectures are compared.
