IDENTITY CREDENTIAL APPLICATION METHOD, IDENTITY AUTHENTICATION METHOD, DEVICE, AND APPARATUS

摘要

The present application provides an identity credential application method, and an identity authentication method, a device and an apparatus. Said method comprises: a first device sending a first message to a second device, the first message comprising identity credential application information of the first device; the first device receiving a second message sent by the second device, wherein the second message comprises processed identity credential application information, and the processed identity credential application information is obtained after the identity credential application information of the first device is signed by a private key of the second device, or is obtained after being subjected to symmetric key encryption; and the first device sending a third message to a third-party device, the third message comprising the processed identity credential application information and is used for requesting registration of an identity credential of the first device to the third-party device, the third-party device and the second device trusting each other. The technical solution can ensure the security of the process of a device registering an identity credential, improving the coverage of an authentication device.
