Recently, an enhanced spatiotemporal chaotic image/video cryptosystem was proposed by Rhouma and Belghith. This paper demonstrates that the enhanced cryptosystem is not secure against the following three different classical types of attacks: chosen plaintext, chosen ciphertext, and known plaintext. In the three attacks, only a pair of (plaintext/ciphertext) was needed to totally break the cryptosystem.
