Designing cryptographic key generators with low power consumption

The focus of this research is the cryptographic keys generation with low power consumption. The idea of power consumption minimization by using modified structure of LFSR has been proposed. Some pseudorandom non linear pattern generators with low power consumption used in stream cipher cryptography are presented in this paper: the Geffe generator, the Jennings generator, the Beth-Piper stop-and-go generator, the Gollmann cascade stop-and-go generator.
