Abstract EN
A well known cryptographic techniques is Playfair Cryptography, it is considered one of the classical method.
After the invention of different techniques, it is easy to break Playfair.
This paper proposed some way for removal of the traditional Playfair drawbacks.
The Adaptive playfair algorithm proposed in this paper, add more security and complexity to the classical playfair algorithm.
In addition to the use of two keys in form of matrices to encrypt the message, the proposed method works depending on using the odd even positions for the every pairs of the letters.
The odd pairs encrypt through the first matrix key and the even pairs encrypt by using the second matrix, then applying XOR function with the third key to the result.
The resulting cipher text will be in binary form, the plain text obtained by run proposed step backwards.
