Transposition is simpler and more powerful technique than substitution because it not only substitutes the text, but also permutates the text. This paper basically presents some new transposition techniques that can be used in cryptography (N/W Security). In this paper, we have developed the old...
A. Basic Technique It is a slight variation to the Rail-fence technique, let's see its algorithm: In a rectangle of pre-defined size, write the plain-text message row by row. Read the plain message in random order in a column-wise fashion. It can be any order such as 2, 1, 3 e...
So a columnar transposition cipher is a kind of transposition cipher in which the plaintext is rearranged by columns before encryption. It is a commonly used encryption technique that is easy to use and effective for a variety of purposes, like data protection and military communications. It can...
In the previous chapter we learned about transposition cipher, types basic implementation, features and drawbacks of this technique. Now we will see the transposition cipher encryption algorithm and its implementation using different languages like Python, C++, and Java. So first let us see the trans...
Cryptography is an art and science of converting original message into non-readable form. There are two techniques for converting data into non-readable form: 1) Transposition technique 2) Substitution technique. Transposition ciphers us... Malay B. Pramanik,Malay B. Pramanik - 《Ijca Special Is...

Cryptography is the science of writing message in secret code and is an ancient art. There are many techniques to encrypt "plain text" and convert it to the "cipher text". In this paper we made an attempt to enhance "Odd-Even Transposition Technique"[1] and make out the technique more ...
The major problem in symmetric key is the key exchange between the communication parties. Transposition is a simpler and more powerful technique than substitution because it not only substitutes the text, but also permutates the text. The new approach first develops three new transposition algorithms...
A new technique which uses symmetric key-set and bit level transposition of the plaintext data is proposed. This technique is expected to be much faster as compared to the digital encryption protocols, as well as more secure compared to the aged transposition and substitution encryption techniqu...
The proposed technique is evaluated by objective analysis using various image quality assessment metrics, producing promising results in terms of imperceptibility and security. Moreover, the high quality stego images and its minimal histogram changeability, also validate the effectiveness of the proposed...
