Abstract
Roaming spoofing attacks can be initiated during N32-c handshake procedure used for inter-PLMN communication in 5G network. One example solution described herein uses the SEPP to mitigate the N32-c roaming spoofing attacks by cross validating the sender attribute present in N32-c handshake security capability exchange messages against the endpoint identity in the X.509v3 certificate shared during TLS handshake and the remote SEPP identity configured in the SEPP's local database.
