A Review on various security flaws and their possible counter measures over Wireless Sensor Networks

electronics and communication engineering

In the near future, sensor networks are going to be a part of everyday life. Traffic monitoring, military tracking, building safety, pollution monitoring, wildlife monitoring, patient security are some of the applications in sensor networks. Sensor networks vary in size and can consist of 10 to 1,000,000 sensor nodes. They can be deployed in a wide variety of areas, including hostile environments, demanding secure measures for data transfer. Sensor nodes used to form these networks are resource-constrained, which makes these types of security applications a challenging problem. A basic technique to protect data is encryption; but, due to resource constraints, achieving necessary key agreement for encryption is not easy. Cryptographic and authentication protocols have been proposed to protect these networks from outsider intrusions but fail to protect them from the insider ones. most of them focus on the anomaly detection in general assuming that the intrusion is kind of anomalies.
