Claim 12:
13. A system for User Equipment (UE) route selection policy (URSP) rule security, comprising:
a UE configured to receive a set of URSP rules with traffic descriptors with criteria for matching the URSP rules to a packet sent by the UE;
the criteria is set based on at least one of a data network name (DNN), Application Identity (ID), fully qualified domain name (FQDN), or internet protocol (IP)-Tuple;
every time a packet is prepared for transmission, the UE validates the URSP rules before a match of the URSP rules is made to a protocol data unit (PDU) session;
the system verifies a content and signature of the URSP rules have not been altered;
when the URSP rules cannot be verified, the UE accesses a core network to request an update to the URSP rules; and
when the URSP rules can be verified, the UE matches the URSP rules to the PDU session.
