| Abstract | ||
| In this paper a Bank of Linear Feedback Shift Registers (LFSR) is used to design and build a system for cryptography. This algorithm consists of 16 Linear Feedback Shift Registers. When we choose eight Shift Registers for each operation of this system, we get one byte constantly this operation. The external unit consists of three Linear Feedback Shift Registers use for filling the main system to generate the stream cipher of bits (0&1) as a Pseudo Random generator, in which we use the permutation system and this sequence of bits passed the statistical tests. Key words: (LFSR) Linear Feedback Shift Register, Bit Permutation, Pseudo Random Generator, External Unit. | ||
