Thales 5G identity management
Reconciling telcos’ Lawful Interception obligations in 5G SA with user privacy protection
Thales 5G Identity Management provides real-time association between permanent and temporary user identifiers in 5G Stand Alone networks.
-
Advanced LI compliance
Mobile network operators continue to meet their legal responsibilities for LI to LEAs in 5G Stand Alone networks by providing at any time SUPI and SUCI when required by authorities (e.g. Police, agencies…).
-
Enhanced user trust
Users are protected from malicious attacks and illegal use of their identifiers (thanks to user identifier concealment), while benefiting from authorities’ protection in certain severe security circumstances, e.g. Search And Rescue (thanks to 5G identifiers’ association).
-
Easy integration
ULIS Identity Query Function (IQF) and Identity Caching Function (ICF) provide 5G Identity Management either integrated to telco’ Lawful Interception solution or as an independent deployment.
-
Comprehensive portfolio
Thales is the only vendor covering all 5G identity association steps:
- From identification (via 5G SIM / eSIM and IMSI catchers)
- To de-identification (5G SIM/5G eSIM, HSM-based SUPI encryption, OTA platform)
- To re-identification (via SUPI/SUCI association and IMSI catchers)
5G SA brings robust user privacy protection via mobile user identity anonymization.
This concealment mechanism renders IMSI catchers ineffective and prevents Law Enforcement Authorities from accessing user’s identity when required for criminal investigation or Search And Rescue.
5G identity association ensures telcos to reconcile their LI obligations in 5G SA towards LEA with maximum user privacy protection.
