Theory of ternary jitter-based true random number generators composed of identical gates

In this paper, we continue to study of a novel family of generators producing true uniform random numbers. The generator consists of a number of identical ternary logic combinational gates. In our previous work, the main attention was dedicated to the schemes composed of the gates in a ring. Other circuits are taken into consideration in this paper. All the units are characterized by time delays that are random and independent. If this time delay has an exponential distribution, then the theory of generator's behaviour is based on the Erlang equations. Some other models are also considered. The features of the multidimensional random vectors produced by the generator are discussed. They can be used for identification of the generator.
