Apple files patent for securing 5G connection resume requests
Apple describes a method for 5G base stations to verify the security level of a phone trying to reconnect to the network. The system checks a specific security code version in the phone's request to ensure the connection is protected before the base station asks the previous tower for the user's data.
In the filing’s own words
System, methods, and apparatus for protecting radio resource control (RRC) resume request message can include sending, by a target gNB (T-gNB), a system information (SI) message indicating a new message authentication code-integrity (MAC-I) capability for the T-gNB to a user equipment (UE), the UE in a radio resource control (RRC) inactive (RRC_Inactive) state; receiving, from the UE, an RRC resume request (RRCResumeRequest) message and an indication of a MAC-I version, the RRCResumeRequest message requesting connection to the T-gNB; sending, from the T-gNB to a source gNB (S-gNB), a Retrieve UE Context Request message indicating the MAC-I version; receiving, from the S-gNB, a Retrieve UE Context Response message; and sending, to the UE, a message based on the Retrieve UE Context Response message received from the S-gNB.
