Examines the hash function based on chaotic maps with changeable parameters and parallel calculations. It appeared to be weakness to attacks that rely on the implementation of chaotic systems on a finite set of states in the digital computer system. We prove that considered function is not collision resistance and 2nd pre-image resistance.
