Abstract

The invention discloses a digital signature authentication method, device and system. The method comprises the steps that a key management center obtains terminal identity information of terminal equipment; The key management center generates a terminal equipment key according to the terminal identity information of the terminal equipment, and distributes the terminal equipment key to the terminalequipment; And the identity authentication node authenticates the terminal equipment according to the key of the terminal equipment. According to the invention, the terminal identity information is directly used as the public key, so that the defects of high terminal certificate authentication cost, high terminal performance requirement and the like in the prior art can be overcome on the premiseof ensuring the terminal authentication security.

Description

technical field [0001] The present invention relates to the field of the Internet of Things, in particular to a digital signature authentication method, device and system. Background technique [0002] At present, the digital signature authentication method used in the industry adopts the method based on the public key infrastructure PKI. The user needs to apply for a certificate for his public key from one or more certification authorities (CA), and the CA issues a certificate for the user's public key. The user's ownership of the public key. Verifying the public key certificate is actually verifying the CA's signature on the certificate. [0003] Therefore, there is a need to pay the CA when the terminal is authenticated, resulting in high authentication costs and high requirements for terminal memory and computing performance, which is not suitable for IoT terminals with low processing levels. Contents of the invention [0004] In view of the above technical problems,...
