Abstract: This paper proposes a Pseudo Random Number Generator(PRNG) based on block cipher of Rijndael, which is called Rijndael PRNG. The results of the security analysis, tests of pseudo random performance and the analysis of phase space reconstruction show that Rijndael PRNG takes on some excellent characters, such as simple method of construction, high security, good performance of pseudo random and easy to be implemented in hardware. Thus, Rijndael PRNG will provide a new choice of PRNG for practical application.
