Image encryption using block cipher and chaotic sequences

作者：

Highlights：

• Propose randomized block ciphers inspired by the Rijndael architecture employing chaotic maps as an entropy source.

• Encrypt images using the randomized version of the Rijndael S-box.

• Propose alternatives to the diffusion layer of the Rijndael that speed up the encryption process.

• Analyze the level of security of the proposed ciphers.
