Overview Although undisrupted and continuous connectivity for wireless devices is hard or perhaps impossible to guarantee, connectivity of these devices has continued to improve and most devices nowadays are almost continuously connected to the internet via some form of wireless access. This improved connectivity enhances user experience but at the same time poses new security concerns. Devices can have several interfaces viz. IrDA, Bluetooth, USB, Serial port, 802.11 etc. Each unguarded interface exposes a potential source of attack. This paper presents an architecture and a proof of concept implementation of a security infrastructure for mobile devices in an infrastructure based pervasive environment. A semantic policy language "Rei" is used to express security policies.
