PRIVATE INFORMATION DISTRIBUTION METHOD AND DEVICE

摘要

Embodiments of the present invention disclose a secret information distribution method. The method includes: receiving, by a network functions virtualization infrastructure NFVI, secret information sent by management and orchestration MANO; creating a vTPM in the NFVI, and writing the secret information into the vTPM; receiving, by the network functions virtualization infrastructure NFVI, a virtualized network function VNF initialization command from the management and orchestration MANO, and creating a VNF; and obtaining, by the VNF, the secret information from the vTPM. Only the vTPM learns of the secret information of the VNF, and therefore the secret information does not go beyond a trusted environment. This ensures confidentiality and integrity of the secret information, and also prevents the secret information from being leaked in a distribution process.
