A 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...
متن کاملA Block Cipher Basing Upon a Revisit to the Feistel Approach and the Modular Arithmetic Inverse of a Key Matrix
In this paper, we have developed a block cipher by using the modular arithmetic inverse of a key matrix. The key matrix is generated by taking the key in the form of twenty-eight numbers, wherein each number is represented in terms of seven binary bits. The encryption is carried out by using the key matrix containing binary bits. The decryption is performed by using the modular arithmetic inver...
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 Modern Hill Cipher Involving a Permuted Key and Modular Arithmetic Addition Operation
In this paper, we have developed a symmetric block cipher by modifying the classical Hill cipher. In this we have made use of iteration process, and introduced a key K0 obtained by permuting the elements of the original key matrix K. This key K0 strengthens the cipher, and it does not allow the cipher to be broken by the known plaintext attack. The avalanche effect and the cryptanalysis clearly...
متن کاملA Modified Feistel Cipher Involving Key Based Substitution, Shifting Of Rows, Key Based Mixing Of Columns, Modular Arithmetic Addition And Shuffling
In this paper, we have developed a block cipher by modifying the Feistel cipher. Here we have taken the plaintext in the form of a pair of matrices and we have introduced a set of operations called key based substitution, Shifting of rows, Key based mixing of columns, modular arithmetic addition and shuffling. In this analysis, the key based substitution and the key based mixing of columns play...
