Pseudorandom byte generator based on shrinking 128-bit chaotic function

摘要

We propose a novel shrinking pseudorandom byte generator based on Ikeda functions with 128 bit computational precision. The result of the analysis shows that the novel scheme ensures a high security in the data encryption process. The computation is based on a GNU portable C library for arbitrary-precision binary floating-point computation with correct rounding, based on GNU Multi-Precision Library.
