A Novel Feistel Cipher Involving
نویسنده
چکیده
In the present investigation, we developed a novel Feistel cipher by dividing the plaintext into a pair of matrices. In the process of encryption, we have used a bunch of keys and modular arithmetic addition. The avalanche effect shows that the cipher is a strong one. The cryptanalysis carried out on this cipher indicates that this cipher cannot be broken by any cryptanalytic attack and it can be used for secured transmission of information. Keywordsencryption; decryption; cryptanalysis; avalanche effect; modular arithmetic addition.

A Novel Feistel Cipher Involving a Bunch of Keys
In this investigation, we have developed a novel block cipher by modifying classical Feistel cipher. In this, we have used a key bunched wherein each key has a multiplicative inverse. The cryptanalysis carried out in this investigation clearly shows that this cipher cannot be broken by any attack. Keywords-encryption; decryption; cryptanalysis; avalanche effect; multiplicative inverse.

In this investigation, we have developed a block cipher by blending a modified Feistel cipher and the advanced Hill cipher. In this analysis, we have made use of a pair of involutory matrices, say A and B which include the keys K and L. Here the size of the plaintext is 1024 binary bits and the size of the keys (both put together) is 256 binary bits. The involutory matrices A and B, the modular...
متن کاملA Block Cipher Obtained By Blending Modified Feistel Cipher And Advanced Hill Cipher Involving A Single Key Matrix
In this investigation, we have developed a block cipher which includes the basic ideas of the modified Feistel cipher and the advanced Hill cipher. In the advanced Hill cipher, as the modular arithmetic inverse of a matrix is the same as the matrix itself, the computations involved in the development of the inverse of the matrix are reduced remarkably. The cryptanalysis carried out in this inve...

متن کاملA Modified Feistel Cipher Involving
In this paper, we have developed a modification to the Feistel cipher by taking the plaintext in the form of a pair of matrices and introducing a set of functions namely, substitute, shifting of rows, mixing of columns and XOR operation with a key. Further we have supplemented this process by using another function called shuffling at the end of each round of the iteration process. In this anal...
