Abstract: This paper presents a new method for implementing TRNGs in FPGA devices. The design is based on filling the chip close to its maximal capacity and exploiting the interconnection network as intensely as possible. This way, there are strong chances for the design to exhibit a nondeterministic behavior. Our design is a computationally intensive core that generates 64-bit numbers, accumulated into a normal, fixed-point accumulator. From the 64-bit words only those bits are extracted that exhibit the maximal entropy. They are then post-processed using the classical XOR-based bias elimination method. The resulting TRNG provides high quality random numbers; other advantages of this new method are its stability and the fact that the design encapsulates all its components in one chip. An explanation of the observed phenomenon is proposed, based on electromagnetic interferences inside the chip and cross talk. A method for developing new designs based on this approach is also proposed.
