Private Message Franking with After Opening Privacy
Serge Vaudenay, Iraklis Leontiadis
Recently Grubbs et al. [GLR17] initiated the formal study of message franking protocols. This new type of service launched by Facebook, allows the receiver in a secure messaging application to verifiably report to a third party an abusive message some send ...
2023Analysis and Improvements of the Sender Keys Protocol for Group Messaging
Messaging between two parties and in the group setting has enjoyed widespread attention both in practice, and, more recently, from the cryptographic community. One of the main challenges in the area is constructing secure (end-to- end encrypted) and effici ...
2022Geoinformation Harvesting From Social Media Data: A community remote sensing approach
Devis Tuia, Alex Hubertus Levering
As unconventional sources of geoinformation, massive imagery and text messages from open platforms and social media form a temporally quasi-seamless, spatially multiperspective stream, but with unknown and diverse quality. Due to its complementarity to rem ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2022Power Yoga: Variable-Stretch Security of CCM for Energy-Efficient Lightweight IoT
Damian Vizár, Reza Reyhanitabar, Emiljano Gjiriti
The currently ongoing NIST LWC project aims at identifying new standardization targets for lightweight authenticated encryption with associated data (AEAD) and (optionally) lightweight cryptographic hashing. NIST has deemed it important for performance and ...
RUHR-UNIV BOCHUM, HORST GORTZ INST IT-SICHERHEIT2021Converse for Multi-Server Single-Message PIR with Side Information
Michael Christoph Gastpar, Su Li
Multi-server single-message private information retrieval is studied in the presence of side information. In this problem, K independent messages are replicatively stored at N non-colluding servers. The user wants to privately download one message from the ...
2020Application of a Low Frequency, Low Power Radio Frequency Positioning System for Real Time Indoor Positioning
Yves Perriard, Alexis Boegli, Pooneh Mohaghegh
This paper focuses on the design and application of low power and low-frequency localization system using received signal strength indication (RSSI). The receiver will wake up from sleeping mode by a modulated magnetic field emitted from a transmitter modu ...
2020Detection Under One-Bit Messaging Over Adaptive Networks
This paper studies the operation of multi-agent networks engaged in binary decision tasks, and derives performance expressions and performance operating curves under challenging conditions with some revealing insights. One of the main challenges in the ana ...
IEEE-INST ELECTRICAL ELECTRONICS ENGINEERS INC2019Optimized Quantization in Distributed Graph Signal Processing
Pascal Frossard, Isabela Cunha Maia Nobre
Distributed graph signal processing methods require that the graph nodes communicate by exchanging messages. These messages have a finite precision in a realistic network, which may necessitate to implement quantization. Quantization, in turn, generates er ...
IEEE2019On the Tradeoff Between Accuracy and Complexity in Blind Detection of Polar Codes
Andreas Peter Burg, Alexios Konstantinos Balatsoukas Stimming, Pascal Giard
Polar codes are a recent family of error-correcting codes with a number of desirable characteristics. Their disruptive nature is illustrated by their rapid adoption in the 5 th-generation mobile-communication standard, where they are used to protect contro ...
IEEE2018Axo: Detection and Recovery for Delay and Crash Faults in Real-Time Control Systems
Jean-Yves Le Boudec, Simon Bliudze, Wajeb Saab
Real-time control systems use controllers that compute and issue setpoints within stringent delay constraints. Failure to do so, due to a crash or delay as a result of software and/or hardware faults, can cause failure of the controlled resources. Recently ...
