Abstract
Technologies for securing a virtualization network function (VNF) image includes a security server to generate a wrapping cryptographic key to wrap a private key of the VNF image and replace the private key with the wrapped private key to secure the private key. During operation, the VNF image may be authenticated by a network function virtualization (NFV) server as needed. Additionally, the signature of the VNF image may be updated each time the VNF image is shutdown to ensure the continued authenticity of the VNF image.
