Abstract

This paper addresses the problem of providing secure access control in broadcast schemes in a wireless network. We consider an environment where clients subscribe to information objects sent via a broadcast onto a wireless network. In this context, a client should only be able to access its objects of interest for its subscription period, and the security system used must not be easily broken. Existing data broadcasting approaches fail to perform well with increased client loads. In this paper, we propose to use the Drop Groups (DG) protocol, that uses a novel grouping criterion. We present the broadcast organization under DG, and demonstrate that our approach is scalable. We use simulation to compare the DG protocol with existing techniques.
