A New Construction of Pseudorandom Number Generator

Journal of Networks, 2014
Random number sequences and RNGs play an important role in trusted computing environments and cryptographic applications. For example, we use random numbers in the generation of keys in TPM. In some web protocols, random numbers are applied to resist replay attacks.
