A Novel Image Encryption Algorithm based on Logistic Maps
Dongming Chen, Yunpeng Chang · INTERNATIONAL JOURNAL ON Advances in Information Sciences and Service Sciences · 2011
Abstract Recently images are widely used and the security of the information which images bring is becoming a serious problem. There are many shortcomings with traditional ciphers to deal with this kind of data. Because of the characteristic of chaos, the chaotic encryption becomes a good choice to encrypt image. In this paper, a new image encryption algorithm based on logistic maps is proposed. In this new algorithm, a secret key of 80-bit and two chaotic logistic maps are employed. We compare the performance of this algorithm with the typical encryption algorithm in some literature. To prove the security of the algorithm, we carry on the experiments and analysis on the correlation, NPCR, UACI and sensitivity. All the results show that our scheme is efficient and safe.
