| Abstract | ||
| The strong eof stream cipher system depends on the strong of keystream generator. The generator generates pseudo-random-sequence which it passes randomness tests. Non-linear stream cipher based on J-K flip-flops has a number of shortages. This shortage is failure of randomness tests and success of correlation attacks. In this papers, J-K flip-flops is developed by inserting additional logic functions. It leads to improve the generator to pass randomness tests. Also, the non-linear complexity is increased and correlation attack is faced | ||
