摘要

Multimedia file like audio demands special encryption technique due to its large data capacity without compromising correlation between it's original and encrypted version (closer to zero). Most of the popular block cipher techniques work on multiple rounds whereas the proposed scheme guarantees the necessary low correlation between the original and the encrypted file without multiple rounds. The unique feature is that the consecutive blocks use different keys derived from the original one using the proposed key chaining algorithm and experimental results show that the correlation between the consecutive keys is also close to zero. The used encryption technique is based on DNA encoding with logistic chaotic map using the generated chain of keys. Furthermore, the concept of channel shuffling is introduced to make the encrypted data more secure. The experimental results confirm that the correlation between the original and ciphered block is close to zero and number of samples change rate value is close to 100. Again correlation between the two consecutive ciphered blocks is also close to zero, which conforms the acceptability of proposed scheme.
