Embodiment Construction
[0027] Such as figure 1 As shown, the present invention is a random number generator based on a two-input two-output logic gate asymmetric autonomous Boolean network, including an entropy source circuit (1) and an entropy sampling circuit (2);
[0028] The entropy source circuit (1) consists of a two-input two-output exclusive OR gate XNOR0 and 11 two-input two-output exclusive OR gates XOR1-XOR11 to form an autonomous Boolean network, the same-or gate XNOR0 and exclusive OR gates XOR1-XOR11 The nodes in the network are formed, and the adjacent nodes and non-adjacent nodes are coupled and connected to each other to form an asymmetric network topology, so that the same-or gate XNOR0 can oscillate, so that each node of the entropy source circuit (1) continuous oscillation;
[0029] The entropy sampling circuit (2) is composed of three D flip-flops and a three-input XOR gate XOR12, and the signal input ends of the three D flip-flops are respectively connected with three randomly...
