DeepSec 2022 Talk: End-to-end Health Data Privacy Using Secure 5G Data Channels – Dr. Razvan Bocu

Sanna/ August 30, 2022/ Conference/ 0 comments

The integrated collection of personal health data represents a relevant research topic, which is enhanced further by the development of next generation mobile networks that can be used in order to transport the gained medical data. The gathering of personal health data has become recently workable using relevant wearable personal devices. Nevertheless, these devices do not possess sufficient computational power, and do not offer proper local data storage capabilities. This paper presents an integrated personal health metrics data management system, which considers a virtualized symmetric 5G data transportation system. The personal health data is gained using a client application component, which is normally deployed on the user’s mobile device, regardless if it is a smartphone, smartwatch, or another kind of personal mobile device. The collected data is securely transported to the cloud data processing

DeepSec 2021 Talk: Post-quantum Encryption System for 5G – Maksim Iavich

Sanna/ October 13, 2021/ Conference

Nowadays, many leading scientists and experts are actively working on the creation of quantum computers. On October 23 2019, Google announced that it has achieved quantum supremacy. This means the great speedup of the quantum processors compared to the fastest classic computer. On December 06 2020, scientists in China also announced that they also achieved quantum supremacy. Quantum computers will probably destroy most cryptosystems that are widely used in practice. A variety of “resistant to quantum attacks,” alternatives are developed. These alternatives are hash-based, code-based, lattice-based and multivariate crypto schemes. However, to date a number of successful attacks is recorded on the given system. It is also shown that these schemes have efficiency problems. The amount of traffic carried over wireless networks and the number of mobile devices (including IoT) are growing rapidly and

Translated Article: EU Prosecutors call for Security Holes in 5G Standards

Sanna/ June 3, 2019/ Communication, Discussion, High Entropy, Security

EU-Strafverfolger fordern Sicherheitslücken in 5G-Standards for fm4 by Erich Moechel The telecoms are to be forced to align the technical design of their 5G networks with the monitoring needs of the police authorities. In addition, security holes in the 5G protocols are required to enable monitoring by IMSI catchers. Gilles de Kerchove, EU counter-terrorism coordinator, warns against the planned security standards for the new 5G mobile networks. The reason for this are neither network components of the Chinese manufacturer Huawei, nor technical defects. De Kerchove’s warnings are directed against the planned high degree of network security, according to an internal document of the EU Council of Ministers, available to ORF.at. These measures to protect against criminals as well as the planned 5G network architecture stand in the way of the installation of backdoors for

DeepSec 2018 Talk: New Attack Vectors for the Mobile Core Networks – Dr. Silke Holtmanns / Isha Singh

Sanna/ September 19, 2018/ Conference

DeepSec has a long tradition of tackling the security of mobile networks and devices alike. The first DeepSec conference featured a presentation about the A5/1 crack. Later one we offered trainings covering mobile network security and weaknesses. So we are proud to announce Isha Singh’s and Silke Holtmanns’ talk about new attack vectors. Here is a brief summary: “Roaming or being called from abroad is being something we take for granted.”, says Silke Holtmanns. “Technically it implies that large networks communicate with each other across geographical and political boundaries. Those communication and the network behind is not well known and understood by most cellular users. This network, its background, security and usage will be explained. We will highlight the attack vectors for 2G, 3G and 4G networks and give an outlook on 5G. We
