Fake It Till You Make It: Data Augmentation Using Generative Adversarial Networks for All the Crypto You Need on Small Devices

Deep learning-based side-channel analysis performance heavily depends on the dataset size and the number of instances in each target class. Both small and imbalanced datasets might lead to unsuccessful side-channel attacks. The attack performance can be improved by generating traces synthetically from the obtained data instances instead of...

Minimally-Interactive Protocols for Privacy-Preserving Set and Multiset Operations Between Multiple Parties

In our increasingly digital society, we are making a growing amount of data available to computers, networks and third parties. As a consequence, our sensitive data is in danger of getting exposed. The field of multi-party computation attempts to mitigate this by studying protocols that enable parties to perform their operations digitally,...

An Elliptic Curve Cryptography Acceleration Core for OpenVPN on an FPGA Softcore

Elliptic Curve Cryptography (ECC) performance is a major performance bottleneck when serving many VPN clients from a single server on a low-frequency FPGA softcore CPU. Using an area-efficient Elliptic Curve Point (ECP) multiplication accelerator core on the same FGPA, a much higher amount of clients can be served using the same FPGA chip. Using...

Cryptografie met elliptische krommen

Digitalization of sensitive information such as bankaccounts enforces privacy to be ensured. Mathematical objects called elliptic curves have ensured exchange of this type of information due to their algebraic structure. The security relies on so called ECDLP and solving these types of problems, but there has yet to be found an efficient...

Enhancing Privacy in Smart Home Ecosystems Using Cryptographic Primitives and a Decentralized Cloud Entity

Within the phenomenon known as the Internet of Things (IoT), an enormous growth is taking place. IoT systems exist in different ways, ranging from industrial applications to user focused systems. A specific subset of a user-focused IoT system is found as Smart Home environments. At Smart Homes, themultiple Smart Objects or Smart Devices are...
