An Enhance Security of Play Fair Cipher Using a Simple Columnar Transposition Technique With Multiple Rounds (SCTTMR)

ABSTRACT-
In this paper, we have made use of a traditional Playfair cipher technique with Simple Columnar Transposition Technique with Multiple Rounds (SCTTMR). After applying SCTTMR we got the actual cipher. Our main focus is on the Playfair Cipher, its advantages and disadvantages. Finally, we have proposed methods to enhance the Playfair cipher for more secure and efficient cryptography which provide difficulty in identifying individual diagram.

KEYWORDS-
