Abstract
A method for a serving network to selectively employ perfect forward security (PFS) based on an indication from a home network is described. The method includes receiving, by the serving network, a PFS indicator from the home network; determining, by the serving network, whether the PFS indicator indicates that the home network has instructed the serving network to employ PFS for communications with a piece of user equipment; and performing, by the serving network, a PFS procedure with the piece of user equipment in response to determining that the PFS indicator indicates that the home network has instructed the serving network to employ PFS for communications with the piece of user equipment.
