Abstract
In a key management method performed by a terminal, a device key including a device public key and a device private key is generated in a security zone. A local device parameter and the device public key are transmitted to a certificate authentication server. A device certificate fed back by the certificate authentication server is received by the terminal. The signature data of the device certificate is generated by signing the device parameter and the device public key by using an authentication private key of the certificate authentication server. The terminal then stores the device private key and the device certificate in the security zone.
