Practical Encoded Processing

Embedded distributed systems are becoming increasingly complex and interconnected. Some of the challenges in building such systems are safety, i.e., the ability to operate correctly even in the face of arbitrary hardware errors, and security, i.e., the ability to withstand hacker attacks. In this paper, an approach to improve both safety and security for embedded distributed systems with low performance overhead is proposed. Preliminary results indicate that applications hardened using the proposed technique have less than 2x performance overhead and fault coverage of 99.9% (assuming no control flow faults).
