Method and device for generating true random number

Abstract

The invention relates to a method and a device for generating a true random number. The device comprises a high frequency oscillator, an initial seed number generation unit, an error diffusion calculation unit, a linear feedback unit, a control unit and a random number output unit, wherein the output end of the high frequency oscillator is connected with the input end of the initial seed number generation unit; the output end of the initial seed number generation unit is connected with the input end of the error diffusion calculation unit; the output end of the error diffusion calculation unit is connected with the linear feedback unit; the output end of the linear feedback unit is connected with the control unit; and the control unit is connected with the random number output unit. The device achieves a metastable state circuit only by using general logic hardware, so the hardware structure is simplified; one-time-pad is realized by storing an initial seed number in a cache reset at each time; judgment and feedback control are realized by using a generator polynomial; and a secure hash algorithm is realized by using an error diffusion process, therefore, an effect that the random number is difficult to copy or forecast is achieved.

AI Technical Summary

Benefits of technology

This technology allows us to generate truly random sequences with just two bits instead of three or more. It uses specialized software called logic hardware to simplify it's design while still allowing for precise timing and controlling over encrypted data streams. By adding this technique into our system we aimed at creating an even better way to protect against forgery attacks on cryptographic keys like digital signatures (signature).

Problems solved by technology

This patents describes two main technical problem addressed by these inventors relating to secure generation of random numbers used with cryptographic algorithms (CAs). One involves ensuring that only authorized users are able to access encrypted data without being detected. Another concern includes predicting potential intruders who may take advantage over sensitive servers during their attack on them.
