Common approaches and trends in construction of hash functions based on chaotic maps were analyzed. Were pointed out that often the real properties of such hash functions are not as expected. Causes of vulnerabilities and flaws in a hash function based on chaotic maps were identified. Principles and guidelines on the use of discrete approximations of chaotic maps for their construction were developed.
