Security Vulnerability and Robust Security Requirements using Key Management in Sensor Network
- Jaykumar Shantilal Patel, Vijaykumar M. Chavda
Sensor network is an amalgamation of hundreds or thousands of sensor nodes. These nodes have sensing, computing and processing potentiality. The sensor network is generally deployed in the hostile environment where the security is very essential. Nowadays security is an important issue in almost every network. Sensor network bears from many constraints like computational potentiality, limited memory, limited energy, limited resources, vulnerability to physical capture etc. These constraint based sensor network makes security as a challenging task. The various attacks at each layer are usual. Resource limitations nature of sensor network makes these attacks even more dangerous. The paper concern the various attacks at each layer in layer architecture of sensor network protocol stack. Keyword: Sensor network Security, Layer architecture, Attacks.
