Abstract

The invention provides a true-random-number generator based on an autonomous boolean network structure. The generator is used to solve the technical problem of poor entropy source stability existing in existing true-random-number generators, and includes an oscillating circuit and a sampling circuit. The autonomous boolean network structure formed by N+1 logic gates is adopted for the oscillatingcircuit. One input port of one of the logic gates is connected with an output port of a right neighbor logic gate, another input port is connected with an output port of a logic gate after k left spacing logic gates, and the last input port is connected with an output port of the one of the logic gates through a time delay self-feedback circuit. The sampling circuit includes N+1 D flip-flops and an exclusive-or gate. Input ports of the flip-flops are connected with the output ports of the logic gates of the oscillating circuit. Input ports of the exclusive-or gate are connected with output ports of the flip-flops. An output port of the exclusive-or gate is used as an output port of the true-random-number generator. According to the generator, entropy source stability is not impacted by thenumber of nodes, and random-number output frequency can reach 300MHz. The generator is used in the field of secure communication.

Description

Technical field [0001] The invention belongs to the technical field of digital circuits, and relates to a true random number generator, in particular to a true random number generator based on an autonomous Boolean network structure, which can be used in the field of secure communication. Background technique [0002] Random numbers have a wide range of applications in cryptography and information security systems. One of its main uses is as a key. In modern information security systems, the security of the system completely depends on the generation efficiency and quality of the random number sequence, so a true random number generator with high security is very important to a cryptographic system. [0003] The commonly used true random number generator is generally composed of an oscillating circuit and a sampling circuit. The oscillating circuit is used to generate an analog signal with noise; the sampling circuit is used to sample the analog signal with noise and output a digit...
