A novel parallel random number generator for wireless medical security applications

A novel parallel random number generator (RNG) based on two dimensions feedback shift register (2-DFSR), genetic algorithm (GA) and cellular automaton (CA) algorithms is proposed for wireless medical security applications. The measurement results demonstrated that the RNG can successfully pass the NIST 800-22 statistical test suite. The highest bit rate is 16 Mbps. The typical power consumption is 61.81 μW. Its energy efficiency is 3.86 pJ/bit.
