True random number generating device and generating method

Abstract

The invention provides a true random number generating device and generating method. The generating device comprises a control module, a random number generating module and a random number reading module. The random number generation module comprises a spin orbital moment layer and a plurality of magnetic tunnel junctions arranged on the spin orbital moment layer. The control module is used for forming a random number generation signal based on a random number generation instruction of a user; the random number reading module is used for inputting a preset signal to the two magnetic tunnel junctions based on the random number generation signal transmitted by the control module and obtaining a random number output signal based on the discharge condition of the preset signal. According to the invention, the problems of high hardware overhead, limited working frequency and high power consumption of a true random number generator in the prior art can be solved.

Description

technical field [0001] The invention relates to the technical field of spintronics and security applications, in particular to a true random number generating device and a generating method. Background technique [0002] True random number generator (TRNG) is one of the core circuits of hardware security, which is mainly used in key generation, data encryption and message authentication. With the explosive growth of network entities, the application scenarios of hardware security have also expanded from host computers to products such as mobile phones, tablets, and wearable devices that are more portable, low-cost, low-power consumption, and high-performance. Moreover, the continuous increase in the number and complexity of networks imposes increasingly high security requirements on applications. Traditional security circuits consist primarily of transistors, creating successful security primitives and protocols. However, most of the current security circuits not only have...
