Ring oscillators (RO’s) are elementary blocks widely used in digital design. Jitter is unavoidable in RO’s, its presence is an undesired behavior in many applications, as clock generators. On the contrary, jitter may be used as the noise source in RO-based true-random numbers generators (TRNG). Consequently, jitter measure is a relevant issue to characterize a RO, and it is the subject of this paper...
This paper describes the implementation of a system for measuring entropy. The design was optimized to be implemented in a simple and small microcontroller, achieving acceptable accuracy. The system allows measuring the entropy of internally code-generated signals, and also, sampled external analog signals. The development board used M1AFS-embedded kit of Actel. In the FPGA (Field Programmable Gate...
