Now a day information security becomes complex and more important problem. Encryption/decryption can be an important tool to help in improving information security. In this paper work, I developed techniques for securing data to avoid hacking as well as providing the user with some additional features such as key for integrity and validation of user. In this technique one can secure any type of files using Fibonacci series. The proposed encryption/decryption algorithm is loss-less, key-dependent. The performance of the popular symmetric key algorithms including DES, 3DES, AES, Blowfish, are compared with Fibonacci Series encryption/decryption by encrypting input files of varying contents and sizes. The present Fibonacci encryption/decryption algorithm is implemented in C sharp language, and tested on two different Intel processors and compared its performance. The results reveal that Fibonacci encryption/decryption is the fastest among symmetric algorithms.
