New Cryptography Algorithm to Provide Security for Wireless Sensor Network
Keywords:
WSN, cryptography, security, ASCIIAbstract
Wireless Sensor Network contains tens to hundreds of nodes used to monitor the environment conditions. The data monitor by these nodes is sent to the main location. This data can be humidity, pressure, temperature, density, etc. Current applications of WSN are area monitoring, Health care monitoring, Forest fire detection, Water quality monitoring, battlefield monitoring, etc. Many of these applications can have sensitive data to transfer to the base station. This data can be forged by the adversary during its transfer. Hence security is one issue in Wireless Sensor Network. The recent research shows that the security can be improved using modified cryptographic algorithms in the sensor network. In this paper, we propose one simple cryptographic algorithm using ASCII values of original data. This algorithm can be used to encrypt the sensed data before its transfer.
