„Obstacles to surveillance“: How authorities insecure 5G telephony

In the fifth generation of mobile communications, encrypted and anonymous connections are technically feasible. Police and secret services, however, provide new interception possibilities

Following the auction of frequencies, mobile operators are building the new 5G network. This fifth generation of mobile phones is considered particularly secure because of its concept of „Privacy by Design“. Connections can be encrypted end-to-end, which makes interception much more difficult. The device numbers of the telephones and the unique identification of the SIM cards are also transmitted in encrypted form. Under 5G, the registered mobile phones also recognize suspicious mobile cells. This makes the IMSI catcher currently in use unusable for locating and listening to telephones in the vicinity.

The new possibilities for encryption and anonymisation are causing police forces and secret services headaches. The German Federal Ministry of the Interior complains of „additional technical hurdles in the monitoring of telecommunications and the implementation of technical investigation measures“ and announces „adjustments“ of the telecommunications legislation. „„Obstacles to surveillance“: How authorities insecure 5G telephony“ weiterlesen

Surveillance of 5G: Governments plan to change laws

5G telephony makes communication more secure. Connections, subscriber and device identifiers are partly encrypted, also conventional IMSI catchers become useless. Providers could therefore be forced to install new surveillance technology.

With Multi-Access Edge Computing (MEC), the fifth mobile phone generation (5G) decomposes the transmission of telephone calls into individual stages and and encrypts them. Telecommunications providers no longer process the traffic centrally, but via various network edges. The metadata and content is only decrypted at these decentralized nodes.

That means that with 5G telephony, communication becomes much more secure. This poses a problem for police forces and secret services. „Surveillance of 5G: Governments plan to change laws“ weiterlesen
