Abstract :
A novel pseudorandom bit generator is presented. It is based on a shift register with a dynamic linear feedback, which, compared to the linear feedback, improves its inviolability property. The proposed circuit exhibits statistical characteristics similar to a linear feedback pseudorandom bit generator with equivalent length. Moreover, the proposed topology, evaluated with the most common randomness tests, gives excellent results
