%X Based on the entropy criterion and n-dimensional uniform distribution of nonlinear digital filter (NDF), we present an efficient NDF-based seudorandom bit generator (NDF-PRBG) for chaotic stream ciphers. The cryptographic properties of the proposed NDF-PRBG are analysed, and some experiments are made. The results show that it has desirable cryptographic properties, and can be used to construct secure stream ciphers with high speed.
