Off-line equipment security authentication system based on PUF technology and implementation method

Abstract

An offline device security authentication system and implementation method based on PUF technology, comprising: a master device and a slave device, the master device comprising: a master controller module, an authentication coprocessor module, a first nonvolatile memory, a first PUF module and a master device communication interface module; the authentication coprocessor is electrically connected with the main controller, the main equipment communication interface module and the first nonvolatile memory respectively; the slave device comprises a slave device communication interface module, a second PUF module, a second nonvolatile memory and an authentication processing module; the authentication processing module is electrically connected with the slave device communication interface module and the second nonvolatile memory, and the second PUF module is electrically connected with the second nonvolatile memory; the master device and the slave device are connected through the master device communication interface module and the slave device communication interface module with the same communication data protocol.

Description

technical field [0001] The invention relates to the technical field of security authentication, in particular to a PUF technology-based offline device security authentication system and an implementation method. Background technique [0002] In recent years, the Internet of Things (IOT) technology has become increasingly mature. Products such as smart lights, smart speakers, smart cameras, and wearable devices have entered people's daily lives, and smart terminals can be seen everywhere. Although the Internet of Things has broad development prospects, However, security issues have become the biggest obstacle to the development of the Internet of Things, and are listed as the number one worry of the Internet of Things. In order to solve the hidden dangers and reduce risks, the use of electronic equipment in some important occasions requires safety certification. The device is a slave device, and the device used to perform security authentication is the master device. When the...

Problems solved by technology

When the symmetric encryption algorithm is used, the master device and the slave device need to store the same key. If the key of one of the master device or the slave device is compromised, all the master and slave devices will be cracked; when the asymmetric encryption algorithm is used At this time, the algorithm has a large amount of calculation, high power consumption, long security certification time, and the corresponding physical cost of the master and slave equipment increases, which is not suitable for market applications
