Efficient non-interactive anonymous communication
Eskeland, Sigurd; Boudko, Svetlana (Journal article; Peer reviewed, 2024)Methods for untraceable and anonymous communication, such as anonymous routing networks and dining cryptographers networks, are in general very complex and suffer from high performance overhead of a minimum order of ... -
A Generic Privacy-preserving Protocol for Keystroke Dynamics-based Continuous Authentication
Baig, Ahmed Fraz; Eskeland, Sigurd (Chapter, 2022)Continuous authentication utilizes automatic recognition of certain user features for seamless and passive authentication without requiring user attention. Such features can be divided into categories of physiological ... -
Novel and Efficient Privacy-Preserving Continuous Authentication
Baig, Ahmed Fraz; Eskeland, Sigurd; Yang, Bian (Journal article; Peer reviewed, 2024)Continuous authentication enhances security by re-verifying a user’s validity during the active session. It utilizes data about users’ behavioral actions and contextual information to authenticate them continuously. Such ... -
Privacy-preserving continuous authentication using behavioral biometrics
Baig, Ahmed Fraz; Eskeland, Sigurd; Yang, Bian (Journal article; Peer reviewed, 2023)Continuous authentication modalities collect and utilize users’ sensitive data to authenticate them continuously. Such data contain information about user activities, behaviors, and other demographic information, which ... -
Privacy-preserving greater-than integer comparison without binary decomposition
Eskeland, Sigurd (Chapter, 2020)Common for the overwhelming majority of privacy-preserving greater-than integer comparison schemes is that cryptographic computations are conducted in a bitwise manner. To ensure secrecy, each bit must be encoded in such ... -
Security in Android smartphone, Confidentiality in IoT-enabled Smart Grids, and Fault-tolerant privacy-preserving in AMS
Abie, Habtamu; Boudko, Svetlana; Eskeland, Sigurd (NR-notat;, Research report, 2020)The report summarizes the three journal papers which address security in android smartphone, confidentiality in IoT-enabled smart grids, and fault-tolerant privacy-preserving in AMS, respectively. -
