Stable Image Encryption Algorithm Based on Expanded One-dimensional Chaotic Jumping and Parallel Encoding Operation Grouping

The current algorithm of encrypting images uses low-dimensional chaotic systems with a limited key space and poor security, while high-dimensional are difficult to implement inefficient. Additionally, if image encryption algorithms use fixed DNA encoding rules, they could be cracked; dynamic coding can easily deviate from optimal solutions, thus causing instability. Based on this, novel technique for is presented in this article. It possible avoid linear correlation the sequence by randomly jumping two uncorrelated one-dimensional chaoses. Meanwhile, numerous results generated parallel grouping groups operations, solution then selected based results, thereby minimizing ciphertext instability some extent. According experimental produces high-security, plaintext-sensitive, non-cracking encrypted images. Furthermore, excellent both color sized images, applicable wide variety applications.
