Abstract

The invention relates to a random noise resource and a manufacturing method thereof. The random noise source comprises a two-end semiconductor superlattice device which is fixed on a microwave printed circuit board and electrically connected with the microwave printed circuit board, wherein the two-end semiconductor superlattice device comprises a semi-insulation semiconductor substrate, a first semiconductor contact layer, a semiconductor superlattice layer structure and a second semiconductor contact layer which epitaxially grow on the semi-insulation semiconductor substrate sequentially, a first contact electrode and a second contact electrode, wherein the first semiconductor contact layer, the semiconductor superlattice layer structure and the second semiconductor contact layer are made of compound semiconductor materials in the III-V cluster or II-VI cluster; and n-type impurities are doped in the first semiconductor contact layer, a potential well layer in the semiconductor superlattice layer structure and the second semiconductor contact layer respectively. Due to a solid automatic chaotic oscillation characteristic of the semiconductor superlattice device, the random noise resource with true randomness, high quality and high bandwidth is implemented; and flat broadband chaotic signals with bandwidths of greater than GHz are output.

Description

technical field [0001] The invention relates to the technical fields of signal processing and encryption, in particular to a random noise source and a manufacturing method thereof. Background technique [0002] Random noise source technology is an important branch of cryptography. Random noise sources and random number generators have a wide range of applications, and are indispensable key components in encryption systems and various cryptographic security systems. Its working status directly affects the reliability and stability of encryption systems and various cryptographic security systems, and the quality of the random sequences generated is related to the protection strength of cryptographic equipment for information. [0003] A random noise source is at the heart of a random number generator. True randomness, high quality, and high bandwidth are the three basic requirements for high-quality noise sources. First, a high-quality noise source requires that the signal ...
