Abstract: In this faster world peoples shares important information through network and wants strong security while sharing data. So to provide such a strongest security to our data the most popular method is used which is known as cryptography. Cryptography is the art and science of achieving security by encoding messages to make them non-readable. In this paper, we combine the rain fence technique and positions analyze technique to achieve more secure data than the normal transposition technique. To increase security we use such type of techniques.
Keywords: cryptography, transposition technique, rail fence technique, position analyze technique, cipher text, plain text.
