Abstract:
1. A method for updating a device certificate trust list in a client device to establish IP network connectivity or transport layer security, comprising: determining, via the client device, that a certificate of a chain of trust of a sub-network is absent from the device certificate trust list; accessing, via the client device, the sub-network in protected mode if the certificate of the chain of trust of the sub-network is absent from the device certificate trust list, where the protected mode enables limited sub-network access and enables acceptance of certificate trust list update messages from a certificate trust list provider; receiving, in the protected mode at the client device via the sub-network, a certificate trust list update from the certificate trust list provider having a MAC layer signaling payload, wherein the certificate trust list update includes a former absent certificate of chain of trust of the sub-network; installing the certificate trust list update within the client device; amending the certificate trust list on the client device based upon the installed certificate trust list update having the former absent certificate of chain of trust of the sub-network; and completing access control authentication process, for accessing the sub-network, using the installed certificate trust list update to establish IP network connectivity or transport layer security for the client device.
