Internet of things equipment identity authentication method and system based on PUF and CPK algorithms, and storage medium

Abstract

The invention discloses an Internet of Things equipment identity authentication method and system based on PUF and CPK algorithms, and a storage medium, and aims to solve technical problems of insufficient security and resource limitation of Internet of Things equipment identity authentication in the prior art. The method comprises the following steps of acquiring challenges and responses of Internet of Things equipment based on PUF, and constructing an equipment fingerprint library by utilizing the challenges and responses of the Internet of Things equipment and a pre-generated equipment identifier ID; generating public and private keys of the Internet of Things device based on a CPK encryption algorithm and the device identifier ID; and performing dual identity authentication of the Internet of Things device based on the device fingerprint library and the public and private keys to obtain an identity authentication result. According to the method, resource consumption of the Internetof Things equipment can be reduced while the identity authentication security of the Internet of Things equipment is improved, and the identity authentication result is more accurate and reliable.

Description

technical field [0001] The invention relates to an authentication method, system and storage medium for an Internet of Things device identity based on PUF and CPK algorithms, and belongs to the technical field of Internet of Things device security authentication. Background technique [0002] With the development of the Internet of Things technology, the security of the Internet of Things has received more and more attention, and it is very important to authenticate the devices in the Internet of Things. Traditional identity authentication is generally implemented by user name and password authentication or PKI / CA technology. The user name and password authentication method is difficult to support a large number of users, and it is difficult to implement in some low-end smart devices, so it cannot be implemented in the physical It is widely used in network security; the PKI / CA system needs to issue digital certificates for each device and smart terminal, and also needs to ex...
