Embodiment Construction

[0030] The present invention will be described in detail below with reference to the accompanying drawings and examples.

[0031] The random number sequence generating method of the present invention is as follows: the quantum tunneling source is used to generate the original random sequence, and the quantum tunneling source is regulated to a certain extent so that the tunneling probability is a stable value, generally 50%. Then detect and record the tunneling situation, if the tunneling is detected, it will be recorded as 1, otherwise it will be recorded as 0, so as to obtain a true random number sequence.

[0032] The true random number generator system of the present invention such as figure 2 and 3 As shown, it consists of a quantum tunneling source, a data acquisition unit, and a data post-processing unit. The data acquisition unit is responsible for receiving the signal from the source of quantum tunneling, and transmitting it to the data post-processing unit for post...

Abstract

The invention provides a method for generating a true random number sequence based on the quantum tunneling effect. The quantum tunneling source is used to generate an original random sequence. After the tunneling probability of the quantum tunneling source is stable, the Topliz-Hash The Toeplitz-hashing method denoises the original random sequence generated after the tunneling probability is stabilized to obtain the final true random number sequence. The elements of the random number sequence generated by the invention are independent of each other, which means that the random number sequence has good randomness; meanwhile, the system for realizing the method is simple and the cost is low.

Description

technical field [0001] The invention relates to the technical field of quantum tunneling, in particular to a method for generating a true random number sequence based on the quantum tunneling effect. Background technique [0002] Human beings have entered the information age, and confidential communication and information security have become more and more concerned issues. Whether it is classical secure communication or quantum communication, the randomness of the random sequence determines the security of the entire information system. If the random number sequence used is cracked, the cryptographic system will be easily broken. The goal we hope to achieve is that even if the cracker has unlimited computing power and knows all the generated sequences, he cannot predict the next random number that the system will generate. Such a sequence is called a true random number sequence. As far as the current cognition is concerned, only by utilizing the indeterminacy of the nature...
