تطوير السرية في نظام التشفير الانسيابي اللاخطي من نوع J-K

Abstract EN

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.
