Performing security analysis of embedded devices is a challenging task. They present many difficulties not usually found when analyzing commodity systems: undocumented peripherals, esoteric instruction sets, and limited tool support. Thus, a signific

Fully Distributed Verifiable Random Functions and their Application to Decentralised Random Beacons

Autor: Jin-Mann Wong, David Galindo, Jia Liu, Mihai Ordean

Publikováno v: EuroS&P

We provide a systematic analysis of two related multiparty protocols, namely (Non-Interactive Fully) Distributed Verifiable Random Functions (DVRFs) and Decentralised Random Beacons (DRBs), including their syntax and definition of robustness and priv

CAOS: Concurrent-Access Obfuscated Store

Autor: David Galindo, Mihai Ordean, Mark Ryan

Publikováno v: SACMAT

This paper proposes Concurrent-Access Obfuscated Store (CAOS), a construction for remote data storage that provides access-pattern obfuscation in a honest-but-curious adversarial model, while allowing for low bandwidth overhead and client storage. Co

Catch me if you can: Using self-camouflaging images to strengthen graphical passwords

Autor: Karen Renaud, Mihai Ordean

Publikováno v: 2012 IEEE 8th International Conference on Intelligent Computer Communication and Processing.

In the last decade graphical passwords have been proposed as a viable alternative to the problematical password. One of the most popular of these is the recognition-based graphical password, where the user clicks secret images from one or more challe
