Abstract
A certificate transfer system includes a first certificate management host and a certificate transfer management host. The first certificate management host is configured to generate a first certificate, sign an electronic device with the first certificate, and transmit a first Internet address to the electronic device to complete a certificate-issuance operation. The certificate transfer management host is configured to store a transfer device list and a second Internet address. When the first certificate management host receives the first certificate issued by the electronic device, the first certificate management host verifies that the first certificate is correct and determines that if the first certificate matches one of the certificates in the transfer device list, the first certificate management host returns the certificate transfer management host address to the electronic device.
