Abstract

The invention discloses a random number generator based on BR-PUF, comprising: a BR-PUF control module, a BR-PUF module, a time-sharing reading module, and an entropy compression module, wherein the BR-PUF module includes a dual-link selection module and n dual-link minimum units; the dual-link selection module controls MUX and DMUX to select an up or down link in each unit according to the excitation signal to form a BR-PUF ring link; the BR-PUF control module controls each single and double link The reset signal at the input end of the NOR gate in the smallest unit of the link changes the working state of the circuit; the time-sharing reading module calculates the time when the ring link appears in a stable state, and repeatedly reads the output state of the ring link according to the interval time to obtain random The number sequence response is read by the entropy compression module in time-sharing, and the hash algorithm is used to compress and iteratively output a random number sequence with full entropy. The random numbers generated by the invention are non-clonable, high in security, simple to realize, high in throughput rate, and significantly improve the utilization rate of the random numbers.

Description

technical field [0001] The invention relates to a random number generator based on BR-PUF, which belongs to the technical field of information security. Background technique [0002] In recent years, people have established complex network systems through sensor networks, the Internet and mobile communication networks. The information data generated by the Internet of Things is growing rapidly, and the frequency of data interaction is getting faster and faster. These data involve various links such as perception, storage, computing, and transmission, and their security is directly related to the development of the Internet of Things industry. [0003] Currently, NVM-based storage mechanisms have the disadvantages of high cost, high power consumption, and vulnerability to intrusive attacks. Therefore, there are great obstacles in the application of traditional authentication methods based on cryptography. This will lead to a large amount of information leakage and threaten ...
