Abstract

In wireless distributed sensor networks, it is important for sensor nodes to communicate securely each other. In order to ensure this security, many approaches have been proposed recently. One of them is to use key predistribution scheme (KPS). In this paper, we shall use the Möbius plane to present a key predistribution scheme for distributed sensor networks. The secure connectivity and resilience of the resulting sensor network will be analyzed in this paper. This KPS constructed in our paper has some better properties than the ones of KPSs constructed in [5],[7] and [9].
