A Framework for Secure Knowledge Management in Pervasive Computing

A feature common too many pervasive computing scenarios is that devices acquire information about their environment from peers through short-range ad-hoc wireless connections and use it to maintain a model of their current context. A fundamental issue in such situations is that knowledge obtained from peer devices may vary in reliability with devices providing incorrect data either inadvertently out of ignorance or other limitations or intentionally in pursuit of malicious or self-serving goals.
