Abstract: Pervasive computing integrates information space with physical space. In this incorporated space, users can obtain digital services non-intrusively anytime and anywhere. Meanwhile, the service brings forth security challenge. Aiming at the unpredictability of the cooperated principals, this paper classifies the present trust research, proposes trust management method of pervasive computing, and resolves two challenging problems.

Key words: pervasive computing, trust management, trust
