SECURE DATA TRANSMISSION WITH HYBRID CRYPTOGRAPHIC TECHNIQUE IN WIRELESS SENSOR NETWORKS

Denial of service (DoS) attack cause severe crash on computing system. To shield our system from dos attack is a crucial task. In the existing system, Multivariate Correlation Analysis (MCA) procedure is used to sense the attacks by anomaly detection method. This gives contribution capable of detecting recognized and unidentified dos attacks successfully by knowledge the prototype of genuine network traffic only. But this method cannot recognize some unfamiliar dos attack. To conquer this dilemma, the proposed method employs two cryptographic system which gives security to both the data and users. Polynomial bi-variate key endow with security to the users by detecting the authorized users to admittance the data in the network. One way hash chain algorithm endow with security to the data. In this system, hash data and wrapped key is an additional security added by every intermediate node. In conclusion the destination user decrypt all the hash data and keys gets the unique message. These methods will exactly sense the attackers.
