Identity authentication method and apparatus

An identity authentication apparatus, applied to a network function virtualization (NFV) system, wherein the NFV system comprises a virtual network function (VNF), and the VNF comprises a first virtual network function component (VNFC) and a second VNFC, the apparatus comprising:

• a processor, configured to generate a public key and a private key of the first VNFC and a public key and a private key of the second VNFC;
• and
• an input/output interface, configured to write or send the private key of the first VNFC and the public key of the second VNFC to the first VNFC, and write or send the public key of the first VNFC and the private key of the second VNFC to the second VNFC, wherein the public key and the private key of the first VNFC and the public key and the private key of the second VNFC are used for identity authentication of the first VNFC and the second VNFC.

• a processor, configured to generate a dedicated key of the first VNFC and a dedicated key of the second VNFC;
• and
• an input/output interface, configured to write or send the dedicated key of the first VNFC and the dedicated key of the second VNFC to the first VNFC, and write or send the dedicated key of the first VNFC and the dedicated key of the second VNFC to the second VNFC, wherein the dedicated key of the first VNFC and the dedicated key of the second VNFC are used for identity authentication of the first VNFC and the second VNFC.
