System and method of establishing trusted operability between networks in a network functions virtualization environment

摘要

A system for establishing a trusted end-to-end communication link between different NFV networks is disclosed. The system comprises a server operating in a trusted security zone and configured to generate and send a trust ticket, a communication request, and disable communication with the first NFV network. The system further comprises a virtual machine executing virtualized network functions and a session border controller. The session border controller is configured to receive the trust ticket, request, and trusted data from the first server; transmit the trust ticket and request to a second session border controller, wherein the trust ticket and request are transmitted to a second server associated with a second NFV network, and receive a response and second trust ticket from the second NFV network, compare the first and second trust ticket for compatibility, and transmit the trusted data if the trust tickets are compatible.
