Detecting false base stations in mobile networks

3GPP standardization takes yet another step to combat false base stations. The security group in 3GPP (called SA3) identified that radio condition information received from devices – which is an integral part of all generations of mobile networks (2G/3G/4G/5G) – could contain fingerprints of false base stations. SA3 has described a solid framework based on this information, enabling mobile networks to reliably detect such false base stations. The framework complements other mechanisms introduced in 5G to protect users against false base stations, for example encrypted long-term identifiers and fresh short-term identifiers. This blog post outlines the framework and describes some practical experiments we have performed in our lab.

IETF and 5G

In the IETF, engineers from all around the world meet to discuss and advance technical specifications that will make the Internet work in the future. Some of those technologies will be used in 5G networks, one of the main focus areas for Ericsson. View these videos to find out more about IETF technologies for 5G systems.

Post-quantum cryptography in mobile networks

Work on cryptography in cellular networks technologies, such as 5G, is driven both in 3GPP and in IETF. Post-quantum cryptography is one important field in this area. Ericsson actively participates in this work, and we recently presented a well-received paper in 3GPP describing the impact of quantum computers and how they affect cellular networks.

This blog post is a slightly revised reproduction of the paper.
