Forestalling tampering of data in wireless sensor network by maintaining integerity using a keyed secure hash function

Abstract

Wireless Sensor Networks WSNs are the recent advanced technology of newlinecomputer networks and electronics The WSNs are gaining a lot of popularity these newlinedays due to their applications in a number of areas WSNs provide an easily newlineimplementable and cheaper solution for many real world problems like data gathering newlinesurveillance, monitoring and control etc However they are also used in a number of newlineapplications where security is a prime concern like military operations or other newlinesensitive projects whereby if the network is compromised then the outcomes can be newlinedisastrous While the set of challenges in sensor networks are diverse we focus on newlinesecurity of Wireless Sensor Networks The proposed scheme Forestalling Tampering of Data in Wireless Sensor newlineNetwork by maintaining integrity using a keyed secure hash function addresses newlineconcerns like efficiency and various security parameters like authenticity newlineconfidentiality integrity and requires lesser processing power newline newline
