Despite Brexit, British police can influence surveillance laws in the EU. The country is also represented in European secret service circles.
Notwithstanding its exit from the European Union, the British police will remain a member of a Standing Heads of Lawful Interception Units based at Europol. The UK is represented there by the National Crime Agency. This was confirmed by the EU Commissioner for Home Affairs, Ylva Johansson, in her answer to a parlamentary question by the pirate Patrick Breyer. The UK is thus the only third country in the group, which otherwise consists exclusively of EU members and the Schengen states Norway, Switzerland and Iceland.
The working group of the departments on telecommunications surveillance had once been founded as a strategic „5G Expert Group“ on the initiative of the German Federal Criminal Police Office. It was supposed to give the authorities access to the new telephone standard, which was actually tap-proof. After this was successfully pushed through in the European and international standardisation bodies ETSI and 3GPP, the group was given a new name and new tasks in October 2021. It is now to ensure that the needs of law enforcement agencies are taken into account when amending surveillance laws at EU level and in the member states. „Encrypted communication: UK remains member of EU interception group“ weiterlesen
So far, German authorities can only notify mobile phones of an impending disaster if their owners have registered beforehand. Soon it will be possible to warn all phones within a certain radius. It is questionable who will decide whether to send such a message.
The German government is another step closer to introducing the „Cell Broadcast“ warning system. Yesterday, the Federal Cabinet agreed on a „formulation aid“ to amend the Telecommunications Act (TKG). If it is passed by the Bundestag, all mobile phones that are logged into a certain mobile phone cell can be warned of an impending event with a text message. The system is not tied to specific phone numbers, but the reception of „cell broadcast“ messages must be activated manually on some mobile phones.
The standard of „Cell Broadcast“ is defined by the 3rd Generation Partnership Project (3GPP), in which worldwide standardisation bodies have joined forces. Accordingly, the service, which was initially only available in GSM networks, can now also be used with LTE and 5G. „Cell Broadcast“ messages can only comprise a maximum of 93 characters. The latest specification extends this to 1,395 characters by sending a total of 15 continuous messages of 93 characters. In addition, the mobile phone emits an alarm tone and vibrates even if it is muted. „Germany: Further step towards the introduction of „Cell Broadcast““ weiterlesen
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
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
