Abstract: A VNF package signing system, comprises an orchestration unit sending an acknowledge of receiving a VNF package including the VNF image, in response to the receiving the VNF package from a sender, a storage unit storing the VNF package and generating a certificate for the VNF package using a private key for at least generating a certificate for signing the VNF package and a HISEE (Hardware Isolated Secured Execution Environment) unit providing the private key in response to the request from the storage unit. The orchestration unit sends the acknowledge of receiving a VNF package when the storage unit successes generating the certificate of the VNF package.
