Dynamic One-Way Key Establishment Scheme in Wireless Sensor Networks

The existing key establishment scheme in wireless sensor networks cannot prevent the adversary from discovering more and more keys of the networks, and thereby, after a long time, the network would be controlled by the adversary. Besides, these schemes also cannot provide a sound method to prevent the replica attacks. In this paper, we propose a dynamic one-way key establishment scheme (called DOK for short hereinafter) which introduces a dynamic one-way key strategy to prevent the adversary from discovering more keys and posing the replica attacks to the networks.
