Abstract

The new millennium heralds the convergence between computing, communication and the intelligent control of our physical environments. Computers embedded in roads, bridges, buildings and vehicles tend to have a long life cycle. Application needs will change and computing, communication and control technologies willevolve rapidly. To keep systems modern, we need technologies to dependably and securely upgrade embedded software in the field. This paper provides a review of our work on how to upgrade embedded control systems without shutting them down, and how to protect the system from bugs and attacks that could be introduced by software upgrades.
