A SURVEY ON EFFICIENT CRYPTOGRAPHIC APPROACH FOR DATA SECURITY IN WIRELESS SENSOR NETWORKS

A new symmetric encryption standard algorithm which is the amalgamation of two different encryption algorithms proposed by Nath et. Al namely TTJSA and DJSA algorithms in randomized method. The algorithm is named as Modern Encryption Standard version–I algorithm. The idea of modern encryption standard is to make a symmetric key cryptographic method which should be unbreakable. The MES version–I algorithm is effective against frequency analysis and spectral analysis. Further improvements can be bit level encryption can be performed on the text files after dividing the plaintext into two text files. Keymanagement, WSN, random pre distribution
