Disclosed in the present invention are a certificate acquisition method and device, comprising: a control device receives a certificate request proxy message sent by a VNF/VNFC instance, said certificate request proxy message comprising authentication information and certificate request information used for requesting a certificate, the control device uses the authentication information to implement authentication of the VNF/VNFC instance, and when authentication is successful, sends a certificate request message to a CA, said certificate request message comprising certificate request information used for requesting a certificate; the control device receives a certificate issued by the CA, and sends same to the VNF/VNFC instance. Thus, an instantiated VNF/VNFC instance requests, by means of a trusted link between a control device and a certificate authentication centre, a certificate issued by the certificate authentication centre, thereby effectively ensuring the validity of the VNF/VNFC instance certificate request, and ensuring, by means of the certificate issued by the certificate authentication centre, the security of a management channel established between the VNF/VNFC instance and the control device. |
