Embodiment Construction

[0014] The present invention will now be described in further detail in conjunction with the accompanying drawings and preferred embodiments. These drawings are all simplified schematic diagrams, which only illustrate the basic structure of the present invention in a schematic manner, so they only show the configurations related to the present invention.

[0015] Such as figure 1 A true random bit stream generator shown includes two parts: a random noise extraction module 1 and a bit stream output module 2 . The random noise extraction module 1 is used to extract the noise at both ends of the Zener diode, and generate a random digital noise signal to the bit stream output module 2. The bit stream output module 2 processes the multi-channel random digital noise and outputs a true random bit stream.

[0016] The random noise extraction module 1 described in the present embodiment is made of N random digital noise generators, such as figure 2 As shown, N is a positive integer ...

Abstract

The invention relates to a true random bit stream generator, which comprises a random noise extraction module and a bit stream output module. The random noise extraction module is used for extracting the noise at two ends of a voltage-regulator diode and generating a random digital noise signal to the bit stream output module; and the bit stream output module processes the random digital noise and outputs the true random bit stream. Due to the adoption of a multi-path noise extraction method, the randomness of the output bit streams is further improved, and the generated random data has good statistical property before postprocessing.

Description

technical field [0001] The invention relates to a true random bit stream generator, in particular, it can be applied to a simple true random bit stream generator that needs to generate high-quality true random numbers. Background technique [0002] Random numbers have important applications in many fields such as gaming industry, computer simulation and random sampling, especially in the fields of cryptography and information security. There are two types of random numbers: pseudo random numbers (PRNG) and true random numbers (TRNG). Pseudo-random numbers are generally generated by computers through mathematical methods. The random numbers generated by it have certain rules. For the same input seed, the output random sequence will be the same. Therefore, in encryption applications, if the attacker has Sufficient computing power can crack pseudo-random number encryption. True random numbers are generated based on some kind of natural noise, completely irregular and unpredic...
