New 5G White Paper Available: Initial Non-Access Stratum Message Security
The NIST National Cybersecurity Center of Excellence (NCCoE) has released the initial public draft Cybersecurity White Paper (CSWP) 36F, Initial Non-Access Stratum (NAS) Message Security, which describes a 5G security feature that protects sensitive information in the Initial Non-Access Stratum (NAS) Message and explains how organizations can verify these protections in deployed 5G networks.
This white paper is part of the NCCoE’s work to accelerate the adoption of 5G security features by demonstrating their implementation on our operational 5G security testbed and providing actionable implementation guidelines to help network operators enhance the cybersecurity and privacy of 5G systems and supporting infrastructures.
Current 5G standards include specifications to address cybersecurity and privacy challenges present in previous generations of cellular systems. In 4G, the initial handshake message used to establish a connection between the device and the network—the Initial NAS Message—was sent without encryption or integrity protection. This leaves the 4G...
