In the past few years use of internet has grown dramatically. Lots of sensitive data is being stored and transferred on-line via Internet. This leads to the need of securing data. Many data security techniques arise due to this among which are cryptographic techniques. Cryptography is art of converting plain text(P.T.) into Cipher Text(C.T.) our proposed work is combination of such two techniques Ceaser Cipher and Rail Fence Algorithm with some modification in Rail Fence algorithm. When both of these techniques considered individual,it is easy to crack the cipher text obtained. But with combination of ceaser Cipher with modified Rail Fence algorithm provides more security to data being transferred,making cipher to crack typical. © 2016,International Journal of Pharmacy and Technology.
