3GPP 5G Security Architecture (TS 33.501)
3GPP Technical Specification 33.501 defines the security architecture and procedures for 5G Systems. Covers authentication, key management, security between network functions, and user plane security. Key features include: 5G-AKA and EAP-AKA' authentication, SUPI/SUCI privacy protection (subscriber identity concealment), service-based architecture security, network slicing security, and interconnect security (SEPP for roaming). Applicable to all 5G network operators and equipment vendors worldwide. 3GPP specifications are implemented by national regulators and are the basis for global 5G deployment.
