Design hybrid encryption system based on E0 algorithm and A5/3 algorithm in the encryption process

Abstract

The purpose of this paper is to create the safer hybrid system ,the more secure and fast , by the merge A5/3 algorithm with  E0 algorithm, so as to produce bluetooth algorithm relies on block cipher. Some modifications were done on both algorithms in order to correspond the work of each algorithm with other, that would speed up the labor of the algorithm in the calculation of the total time-spent and increases the complexity, which increases in the algorithm security.
