Low-power-consumption true random number generator based on oscillation ring jitter

Abstract

The invention discloses a low-power true random number generator based on oscillation ring jitter. Based on temperature compensation and phase self-correction, a designed circuit has the characteristics of temperature stability and low power consumption at the same time. Aiming at the problem that the frequency and jitter of the CSRO in the entropy source circuit are greatly influenced by the temperature inversion effect, the voltage bias circuit is designed for the grid voltage of the current limiting tube in the current starvation type inverter, so that the temperature stability of the CSROfrequency is improved, the jitter in the CSRO is ensured, and the random number generated by the circuit can meet the randomness requirement. Aiming at the problem that the circuit consumes a large amount of redundant power consumption due to continuous accumulation of inherent deviations in the process of continuously generating random numbers by the circuit, the oscillation phase self-correctioncircuit structure of the oscillation ring is provided, and accumulation of the inherent deviations is effectively avoided, so that the redundant power consumption caused by accumulation of the inherent deviations is eliminated.

Description

technical field [0001] The invention is an IOT application-oriented true random number generator with extremely low power consumption. Background technique [0002] With the promotion of 5G communication and the rapid development of Internet of Things (IOT) technology, it can be predicted that an era of Internet of Everything will come in the near future. The so-called interconnection of everything refers to the interconnection between various physical electronic entities used in daily life, such as: mobile phones, access cards, bank cards, controllers in smart homes, etc. These physical electronic entities store a large amount of user information, including a lot of user sensitive information. Once the information is stolen and sensitive information is leaked, it will pose a serious threat to people's privacy and property. In order to improve the security of information, modern cryptography technology is often used in security systems. [0003] In modern cryptography tec...
