SPLICING MODEL AND HYPER-CHAOTIC SYSTEM FOR IMAGE ENCRYPTION

Hongye Niu – Changjun Zhou – Bin Wang – Xuedong Zheng – Shihua Zhou

    Encryption is an effective way to protect the image information from attacking by intruders in the transmission applications through the Internet. This study presents an image encryption scheme on the basics of the formal model of DNA computing-splicing system and hyper-chaotic system, which utilizes the instinct properties of hyper-chaotic system and splicing model while programming the method. In our proposed algorithm, the quaternary coding is used to split the plain image into four sub-sections so that we can't get the cipher image without any one sub-section. This new method can be used to change the plain image information drastically. The experimental results and security analysis show that our method not only has a good security but also increases the resistance to common attacks such as exhaustive attacks, statistical attacks and differential attacks.

Keywords: image encryption, hyper-chaotic system, DNA coding, splicing model
