Abstract: One of the common techniques of image encryption is to make the algorithms being more complex, however, their performances are not advanced much greater. In this study an improvement in the technique of image scrambling is introduced with unique and simple implementation. The encryption systems in this study are based on two security level using the XOR operation and chaotic sequences. The improved techniques are simple to comprehend by way of software program or hardware. They don’t have to do iterative computation and might convey a very good results. The experimental results display that the set of rules are powerful and have better efficiency and have high scrambling level than the others strategies.
