Wireless Security Aspects of Sensor Netwoks: A Review
In today’s advance technology security is very important aspects for network. Wireless Sensor Networks are used in different areas kinds of many applications in military, ecological, medical, process management, environmental, industrial, agriculture etc. These applications often include the monitoring of sensitive information such as enemy movement on the field or the location of personnel in a building. Security is therefore important in Wireless Security Networks. Wireless Security Networks suffer from many constraints, including low computation capability, small memory, limited energy resources, weakness to physical capture, and the use of insecure wireless communication channels. We summarize the constraints, security requirements, and attacks with their corresponding counter measures in Wireless Sensor Networks. We then present a holistic view of security issues. These issues are classified into five categories: cryptography, key management, secure routing, secure data aggregation, and intrusion detection. In this article we present a study of security issues in Wireless Sensor Networks. We need to develop new framework wireless security of Sensor Networks.
