	Security Challenges for our 5G Connected Society 5G is no longer used to connect only consumers, but the focus is on supporting businesses and critical infrastructure. 5G is different then the previous generations in terms of architecture. Virtualization, IoT devices and Internet technologies made a big mark on 5G. This has consequences in terms of security and how vulnerable we are as a society depending on 5G. New security challenges appear through political tensions e.g., attacks on telecommunication infrastructure in Ukraine, usage of 5G for highly critical purposes like military or through new technologies like combining 5G and satellite communication. Security for mobile network is an evolution, we will outline steps in this evolution that may help to keep us all safe. Slides
11:00	Coffee Break and Poster Session
11:30	Talk 1: Adrian Dabrowski, CISPA
	MobileAtlas: Geographically Decoupled Measurements in Cellular Networks for Security and Privacy Research The distinct services and the ability to form large complex compounds for roaming purposes make mobile networks an attractive research target in their own right. Their promise of providing a consistent service with comparable privacy and security across roaming partners falls apart at close inspection. Thus, there is a need for controlled testbeds and measurement tools for cellular access networks doing justice to the technology’s unique structure and global scope. Slides
12:00	Talk 2: Daan Planqué, Ericsson
	OpenRAN Security in 2024 In the beginning of 2022, the German BSI as well as the European commission presented separate analyses on the security of the OpenRAN standard. The result wasn’t great as many basic information security basics were barely or not present in the respective security standards. At that time, I was working as a security advisor at KPN in their CISO team and spoke publicly about these issues, now I’ve moved over to the security team of the vendor who is the co-chair of the OpenRAN working group. A fitting time to look at what has changed in the security specification since then.
12:30	Lunch Break
13:30	Talk 3: David Rupprecht: Security Testing in 5G
	Challenges and Solutions in 5G Certification Through a European act, commercial 5G networks must certify the security of their network components. However, in the current situation, the existing certification schemes are complex and complicated to apply. This makes it difficult to use them in a broader scope to eventually secure our communication infrastructures. In this talk I address the existing challenges of an operationalization of 5G security certification and describe possible solutions. Slides
14:00	Talk 4: Thomas Attema, TNO
	Confidential Computing and Post-Quantum Cryptography for 6G The Horizon Europe project CONFIDENTIAL6G develops (post-quantum) cryptographic solutions to enhance the privacy and confidentiality guarantees in 6G communication infrastructures. The project analyzes the quantum vulnerabilities of 5G networks and aims to develop a transition strategy towards post-quantum security. Additionally, to facilitate the use of sensitive and confidential information, the project works on the deployment of privacy-enhancing technologies (PETs) such as multi-party computation (MPC), homomorphic encryption (HE), and federated learning (FL). This presentation will provide a general overview of the CONFIDENTIAL6G project, with a focus on TNO’s contribution. Slides
14:30	Coffee Break and Poster Session
15:00	Panel
	A panel of experts will discuss current topics in the context of 5G security and the potential of further community collaboration.
