UCAIPM: Ubiquitous Computing Agile Information Protection Mechanism

In order to improve the security of ubiquitous computing system, UCAIPM, a new novel ubiquitous computing agile information protection mechanism is presented. The protected information includes the identity, location, activity of the entities and their neighbors, the service resource like the currently available devices, the schedule like the developing history of the entities and their neighbors. The SPKI-based authorization technology is used in the mechanism to solve the identification validation, security communication and the security level division. The D-S Evidence Theory is used to compute the trust value for deciding the trust level from the service provider to the ingoing user.
