Abstract

The invention discloses an identity authentication and encrypted transmission system based on hardware fingerprints, which includes a device based on hardware fingerprints and a management center; the device based on hardware fingerprints is provided with sequentially connected physical unclonable functions, entropy value extraction modules, and multiple fingerprints. Extraction module, protocol management and transmission control module; the management center is used to complete the registration of new devices and the distribution of explicit fingerprints. The invention only needs to store legal explicit fingerprints, which solves the problems of large certificate storage and complicated management; adopts double fingerprints (explicit fingerprints and implicit fingerprints) to solve the security problem caused by hardware fingerprint leakage.

Description

technical field [0001] The invention belongs to the field of computers and integrated circuits, in particular to an identity authentication and encrypted transmission system based on hardware fingerprints. Background technique [0002] Physical Unclonable Functions (Physical Unclonable Functions, PUF) refers to the generation of a specific response determined by the physical characteristics of the circuit under a given input, also known as "hardware fingerprint". The physical unclonable function comes from the specific physical information introduced by factors such as process deviation during the chip manufacturing process. Since these factors are unpredictable and difficult to control, the response output is theoretically unclonable. The characteristics of PUF mainly include unclonability, uniqueness, unpredictability, lightweight and tamper-proof, so it is very suitable for identification of chips. The PUF system is essentially a combination of microcircuits, which can e...
