Abstract

The embodiment of the invention provides a digital identity authentication method and device, equipment and a storage medium, and the method comprises the steps: obtaining a system certificate and a terminal user certificate issued by a certificate authority, the system certificate being a certificate of the certificate authority, the type of the system certificate being a display certificate, and the type of the terminal user certificate being the display certificate; the type of the terminal user certificate comprises an implicit certificate or a certificateless certificate. And obtaining an intermediate public key corresponding to the terminal user certificate based on a terminal user private key. And according to the intermediate public key and a system public key, a target public key is generated, the system public key is a public key corresponding to the system certificate, and the target public key is used for authenticating the digital identity of a terminal user. In the scheme, the advantages of the display certificate and other certificates are fused, the establishment of the existing public key infrastructure trust system can be effectively met, the storage space of the terminal equipment can be effectively reduced, the bandwidth overhead is reduced, and the communication efficiency is effectively improved.

Description

technical field [0001] The present invention relates to the technical field of information security data processing, and in particular, to a digital identity authentication method, device, device and storage medium. Background technique [0002] With the continuous development of science and technology, the information security industry has also received the attention and attention of all mankind, and has entered a rapid development track. However, with the advent of the Internet of Things, its requirements for information security and high-speed and low-latency are getting higher and higher. [0003] In the traditional scheme, the existing digital information identity basically adopts the display certificate based on the X.509 certificate. However, the large data displayed for the certificate will occupy a large storage space for the end user, and also reduce the speed of secure communication. Therefore, the traditional solution can no longer meet the requirements of high...
