When Tech MIMICS Reality (SHA2017)

TLS can be limiting, OAuth is a (somewhat working) mess. What would happen if we redesigned things from scratch? Fenrir is a federated protocol built with both heavy security and high flexibility in mind, with lots of new and interesting security properties. #NetworkSecurity about this event: https://c3voc.de

The history of cryptography is a history of failures. Stronger ciphers replaced broken ones, to be in turn broken again. Quantum cryptography is offering a hope to end this replacement cycle, for its security premises on the laws of quantum physics and not on limitations of human ingenuity and computing. But, can our nascent quantum technology implement quantum cryptography securely? The talk introduces today's quantum cryptography techniques, then shows how to compromise their security by exploiting imperfections in engineering implementations. #DeviceSecurity #Science #NetworkSecurity about this event: https://c3voc.de

India has rolled out a 'voluntary' biometric ID card to all of its billion-plus citizens. Which is fascinating from a social, technical and fundamental rights perspective. This talk is about both intended and unintended consequences of this grand experiment, with a focus on the (implicit) assumptions we tend to make about technology. #Society #Privacy #SurveillanceState about this event: https://c3voc.de

We use traceroutes to explore and visualise interconnectedness between devices on the internet (specifically: RIPE Atlas probes). This talk is about exploring the interconnectedness within a country ("are local paths local"), and also about exploring the interconnectedness between hackerspaces. #NetworkSecurity about this event: https://c3voc.de

Although IoT is already embedded in our everyday lives, our security and privacy are sometime left behind for comfort and other reasons, despite the serious impact that IoT vulnerabilities may have on our digital and physical security. Bluetooth Low Energy (BLE), also known as Bluetooth Smart is the most popular protocol used for interfacing IoT and smart devices. Broadly used in the healthcare, fitness, security, and home-entertainment industries, nowadays we encounter BLE in almost every aspect of our lives (e.g. in wearables, sensors, medical devices, security products, etc.). In this lecture I will survey key security issues in the BLE protocol, as well as presenting a possible architecture for BLE Man-in-the-Middle (MitM) attack together with the related necessary equipment. In addition, will introduce some of the available tools and how they can be used to perform penetration-testing on BLE applications and will discuss possible mitigations to secure them. #NetworkSecurity #IoT about this event: https://c3voc.de
