X. K. N : a proposed method for data encryption using XOR and NOT logical gates with LFSR generated keys

Abstract EN

In this paper, a method for data encryption was proposed using two secret keys, where the first one is a matrix of XOR's and NOT's gates (XN key), whereas the second key is a binary matrix (KEYB) key.

XN and KEYB are (m*n) matrices where m is equal to n.

Furthermore this paper proposed a strategy to generate secret keys (KEYBs) using the concept of the LFSR method (Linear Feedback Shift Registers) depending on a secret start point (third secret key s-key).

The proposed method will be named as X.K.N.

(X.K.N) is a type of symmetric encryption and it will deal with the data as a set of blocks in its preprocessing and then encrypt the binary data in a case of stream cipher.
