“…Authors considered the digraph in the plaintext as single units and transformed them into corresponding cipher text digraphs. Authors in [4], have got some better performance by proposing the extended version of Playfair encryption technique. In [5], authors studied, analyzed and compared the hybrid data encryption techniques using Fibonacci series, XOR logic and PN sequence.…”

With the technology advancements and easy availability of internet, every day millions of users share information electronically through emails, file sharing, e-commerce, etc. As, internet is highly vulnerable to various attacks, sending sensitive information over the Internet may be dangerous. One of the ways to protect the sensitive Information is using the cryptographic techniques. So, while sharing sensitive information over the Internet, it should be sent in encrypted form to prevent the access by unauthorized person. Encryption can be defined as the process of transforming information in such a manner that only authorized person can understand the shared information. In this paper, we have taken Playfair encryption algorithm for encryption and modified it by using Fibonacci series. Fibonacci series is used to generate a random key, which is used for encrypting the message in Playfair encryption algorithm. Using Fibonacci numbers and generating random keys provide significant security to shared information.

These days, Information Security is the most summon aspects in the web and network application due to their swiftly origination. Therefore, secure exchanged data over the internet is vital. In this context, cryptography is used that converts information from its normal form into an unreadable form by using encryption techniques. This paper deals with a new solution approach to overcome the shortcomings of the Playfair algorithm. In this paper, the presented PlayfairCBC encryption mechanism makes the cryptanalysis complex. The encrypted text obtained is almost unreadable. The proposed PlayfairCBC algorithm is implemented and number of tests is performed to prove its efficiency. Finally, it has been analyzed on the basis of avalanche effect.

This paper deals with the modification of Playfair cipher. The existing methods of Playfair cipher have been studied such as those implemented on 5X5, 7X4 and 6X6 Playfair matrix. The study of existing methods shows that they suffer from several drawbacks such as limited matrix size, limited key size, prone to brute force attack and frequency analysis. In this paper, the presented encryption mechanism makes the cryptanalysis a very complex process. This has been achieved by first, inserting all the 256 ASCII characters in a sequential order within a 16X16 matrix and second, by changing the rotation mechanism for encryption and decryption. The encrypted text obtained is almost unreadable.
