Implicit Security Authentication Scheme in Wireless Sensor Networks

Wireless sensor networks (WSNs) have wide applications due to these sensor nodes ease of deployment.But the security of WSNs is still an important issue. Some existed approaches mainly rely on cryptography to ensure data authentication and integrity. These approaches only address part of the problem of security in WSNs. However, these approaches are not sufficient for the unique characteristics and novel misbehaviors or abnormal behaviors encountered in WSNs. In this paper we introduce an implicit security authentication scheme technique ,which can authenticate the sensor nodes based on actions they would carry out anyway. From our preliminary findings support that this is a meaningful approach, whether used to increase usability or increase security in WSNs.
