Chaotic Image Encryption Algorithm Based on Information Hiding
Dan Wang · Journal of Information Engineering University · 2014
A chaotic image encryption algorithm based on information hiding is proposed by combining the redundancy of image data and the idea of information hiding. The sub-key is generated by the user key and a 128bit random number,making the sub-key different for every encryption procedure. Hence,the encryption algorithm is resistant to both chosen plain-text attack and chosen cipher-text attack. In addition,the random number used in encryption is embedded in the image by information hiding technique,so that receivers do not need a related random number generator to recover the key. Experimental results show that the algorithm is more secure.
