Breaking an image encryption scheme based on a spatiotemporal chaotic system

作者：

Highlights：

• A cryptanalysis of an image encryption scheme based on spatiotemporal chaos is presented.

• We gave a complete and partial break of the cryptosystem under study.

• We prove that the studied cryptosystem is not sufficiently secure against chosen plaintext attack.

• Results suggest that a partial attach needs smaller number of plain/ciphered images with acceptable perceptual qualities.
