Book ChapterDOI
A Smart Contract for Boardroom Voting with Maximum Voter Privacy
TL;DR: The Open Vote Network as discussed by the authors is a self-tallying voting protocol for boardroom elections that does not rely on any trusted authority to compute the tally or to protect the voter privacy.
Book ChapterDOI
Threshold Attribute-Based Signatures and Their Application to Anonymous Credential Systems
TL;DR: In this paper, the authors proposed threshold attribute-based signatures (t-ABS), which enables a signature holder to prove possession of signatures by revealing only the relevant attributes of the signer, hence providing signer-attribute privacy for the signature holder.
Journal ArticleDOI
Adaptive CCA broadcast encryption with constant-size secret keys and ciphertexts
TL;DR: Boneh, Gentry, and Waters as mentioned in this paper proposed a broadcast encryption scheme with constant-size secret keys and ciphertexts and proved that it is selective chosen-ciphertext secure based on standard assumptions.
Journal ArticleDOI
Stealing PINs via mobile sensors: actual risk versus user perception
TL;DR: There is significant disparity between the actual and perceived levels of threat with regard to the compromise of the user PIN, and the technical understanding of the information leakage caused by mobile phone sensors is studied.
Journal ArticleDOI
TouchSignatures: Identification of user touch actions and PINs based on mobile sensor data via JavaScript
TL;DR: In this paper, the authors examine multiple popular browsers on Android and iOS platforms and study their policies in granting permissions to JavaScript code with respect to access to motion and orientation sensor data, and propose TouchSignatures which implements an attack where malicious JavaScript code on an attack tab listens to such sensor data measurements.
