Abstract:-With the exposure to World Wide Web and emergence of social networks, ecommerce applications and many organizations all over the world produces enormous amount of data. Security of data is the main aspect in today’s computerized world it is important to provide the necessary protection to the information being exchanged over the internet from the intruders. As number of internet users is increasing day by day the number of cyber attacks is also increasing. It is a critical issue to provide security to our computers and networks. Cryptography provides security to data and information on network. In this paper we developed a technique which will help to enhance the data security.

Keywords: Cipher, Cryptography, Encryption Model, Symmetric key cryptography, Rail Fence Technique, Modified Rail Fence

I. INTRODUCTION

Cryptography is a technique which provides security to the data or information being exchanged over the network. It converts the data or information, which is in human readable format, into unreadable format.
The original data in readable format is called plain text and the generated unreadable format is called cipher text. Encryption is transformation of plain text into cipher text and decryption is transformation of cipher text into plain text.

Cryptography is closely related to the development of algorithms for encryption and decryption, where as the term cryptanalysis is used for analysing and breaking the encrypted text. Cryptology is the study of both cryptography and cryptanalysis.
Key plays the major role in the process of encryption and decryption. Cryptography is categorized into two categories according to the number of keys used for encryption/decryption
