AN INTRUSION-AWARE SECURITY MECHANISM IN WIRELESS SENSOR NETWORKS

摘要

The security issue in wireless sensor networks is greatly different from other conventional networks due to node characteristics and specific security requirements. In order to achieve effective authentications among the normal nodes both in deployment and redeployment phase of additional nodes , this paper makes improvements on node identification based on the idea of pair-wise key. Moreover, aggregation sequences and authentication items are constructed for purpose of achieving multi-nodes data-origin authentication. Security analysis and performance evaluation are also addressed.
