In this paper, the structure of chaotic maps and its applications in cryptography and designing cryptographic pseudo random number generators is studied. Three cryptographic pseudo random number generators based on chaotic functions are constructed. High sensitivity to initial conditions in chaotic maps has the main role in the design of proposed algorithms. Proposed algorithms are tested by correlation test and the NIST tests and compared by frequency histograms. The statistical analyses confirm the high quality of the algorithms such as uniformity, independency and randomness properties and the efficiency of proposed algorithms for cryptographic applications..
