There is a need for mechanisms for maintaining and restoring software integrity on deployed systems. Dynamic replacement, removal and addition of components in deployed systems is supported by most component models. This is needed to enable the software on a device to evolve in the period that it is owned by a consumer, but endangers the integrity of the software on these devices. For high volume consumer devices the challenge is to keep the devices operating reliable and robust in the period that it is owned, used and possibly reconfigured by a consumer. To this end, we propose mechanisms and tools, for maintaining system integrity on deployed systems.
