A trust framework for pervasive computing environments

In this paper, we present a flexible, manageable, and configurable trust scheme for the security of pervasive computing applications. Our intention is to develop a trust framework capable of recognizing the difference between "pure" and "managed" ad hoc network structure, and capable of operating in either situation or a combination of both. Our trust framework will minimize the effects of malicious recommendations related to trust from other devices and have the capability to transfer security functionality from devices with limited computing resources to other secure and powerful devices. The presented framework allows administrators to customize trust-related settings in an effort to create a more secure and functional network. Within our framework, wireless devices are broken down into different categories based upon available resources and desired security functionalities. A device's categorization determines its security functionalities and interactions with neighboring devices. By using this flexible framework, administrators can customize devices based upon the network's environment.
