The aim of this contribution is to enhance the security of encrypted image and decrease the execution time. The proposed cryptosystem based on the keystream generator (KSG) inspired from achterbahn-128 characterized by some good properties used for generating the key. The scan pattern is utilized for the mapping of the image encryption. After the generation of the keystream, the image is encrypted vertically using the scan pattern partition, and then the encrypted image is permuted and
more &raquo; ... horizontally. Several tests are done using MATLAB software in order to prove performances of the system, including the statistical tests, the sensitivity analysis, and the security analysis. The proposed technique is simple to implement and has high encryption rate.
