Method and device for generating true random numbers

Abstract

The invention discloses a method and a device for generating true random numbers. The method comprises the following steps of summing and amplifying a process of amplifying quantization errors in the process of analog-to-digital conversion and digital-to-analog conversion and thermal noise introduced into a circuit, and generating the random numbers. According to the method and the device, the symmetrical distribution of noise is converted into random characters of output random sequences '0' and '1', so that the high-quality true random numbers are generated.

Description

Technical field [0001] The present invention relates to the field of security, communication or other fields that require the use of random numbers, and in particular to a method and device for generating true random numbers based on noise amplification in a quantization process. Background technique [0002] In security applications such as digital communications, electronic transactions, and digital signatures, a high-quality random number source is required to generate keys, and then symmetric or asymmetric algorithms are used to complete authentication or identification. Or in dynamic element matching (DEM) and other occasions, a random number generator is also needed. [0003] A well-designed random number is characterized by the unpredictability of the code stream, especially in the field of security, where an attacker cannot make any valuable predictions about the random number based on the design of the random number generator, which requires the noise of the random number ...

According to this principle, existing true random number generators usually use jittered clock sampling, but the code rate of random number output based on the jittered clock sampling method will be limited by the frequency of the sampling clock
