According to some embodiments, systems and methods for binding dynamic host configuration and network access authentication are provided related to, inter alia, interactions between a PAA (PANA Authentication Agent) and a DHCP (Dynamic Host Configuration Protocol) server, such as, e.g., for synchronization between the PANA SA state and the DHCP SA state, such as, e.g., maintaining synchronization when a connection is lost. In some embodiments, systems and methods for binding network bridge and network access authentication are also provided related to, inter alia, interactions between a PAA and a layer-2 switch, such as, e.g., for avoiding service thefts and the like (such as, e.g., MAC address and/or IP address spoofing) in the context of, e.g., the above. In some other embodiments, systems and methods for bootstrapping multicast security from network access authentication protocol are also provided related to, inter alia, key management for protected IP multicast streams, such as, e.g., to avoid IP multicast streams unnecessarily received and/or processed by unauthorized receivers connected to the same layer 2 segment as authorized receivers in the context of, e.g., the above.
