Study on a true random number generator design for FPGA

One of the most debated category of random number generators designs implemented on FPGA is based on free running ring oscillators. This dissertation presents a method of speculating the properties of Galois ring oscillators following the idea that much higher entropy rates can be achieved using this kind of oscillators, in comparison with the classic ring oscillators. This is equivalent with phase jitter increase, which is the main source of randomness in a ring oscillator based random number generator.
