On perspective of security and privacy-preserving solutions in the internet of things
TL;DR: A detailed assessment of the performance of the most used cryptographic algorithms on constrained devices that often appear in IoT networks and the analysis of the usability of upcoming schemes, such as the homomorphic encryption schemes, group signatures and attribute-based schemes are presented.
Proceedings ArticleDOI
Feasibility characterization of cryptographic primitives for constrained (wearable) IoT devices
Aleksandr Ometov,Pavel Masek,Lukas Malina,Roman Florea,Jiri Hosek,Sergey Andreev,Jan Hajny,Jussi Niutanen,Yevgeni Koucheryavy +8 more
TL;DR: The findings show that wearable devices of today have the needed potential to efficiently operate with cryptographic primitives in real time, and it is believed that the data provided during this research would shed light on what devices are more suitable for certain cryptographic operations.
Proceedings ArticleDOI
A Secure Publish/Subscribe Protocol for Internet of Things
TL;DR: In this article, the authors present a novel security framework for the Message Queue Transport Telemetry (MQTT) protocol based on publish/subscribe messages in order to enhance secure and privacy-friendly Internet of Things services.
Book ChapterDOI
Optimization of Power Analysis Using Neural Network
TL;DR: This paper proposes and realizes an optimization of this power analysis method which improves the success rate to almost \(100\,\%\) and compares the results of the optimized method with the original implementation.
Book ChapterDOI
Unlinkable attribute-based credentials with practical revocation on smart-cards
Jan Hajny,Lukas Malina +1 more
TL;DR: A novel cryptographic scheme which allows both expired user revocation and de-anonymization of malicious users on commercially available smart-cards and is provided on .NET V2+ and MultOS smart-card platform.
