| Abstract: | Rijndael is famous for its efficiency and reliability. The encryption means put forward by this paper is an improvement and application of Rijndael in digital images. The experiments proves the security of the image basically depends on the initial value of the chaos sequence. Besides, the encryption is completed at a high speed through checking S-box. |
