Abstract
Nowadays, privacy is becoming more important in data storage and transmission. Images are widely used in several processes. Therefore, the protect ion of image data from unauthorized access is important. Image encryption plays a significant role in the field of i nformation hiding. Encryption is a means to achieve that privacy. It was invented for that very purpose. This paper is introduced to analysis and design a chaos based image encryption technique using the method of shuffled operation. In this new technique, a secret key of 128-bit and shuffled maps are employed. We compared the performance of new technique with the typical encryption technique in s ome literature. The proposed system has the advantage of larger key space; smaller iteration times, high security a nalysis, correlation analysis and entropy analysis will carry on.
