In this paper, we introduce a new security paradigm, called security clustering, for pervasive computing environment that enables network-wide defend against increasing evolutionary attacks on the heterogeneous network and hosts. Security clustering make use of dynamic security context exchange between cluster members and distributed information sharing to achieve scalable and efficient coopera...
