Pairwise key establishment is a fundamental security service in sensor networks; it enables sensor nodes to communicate securely with each other using cryptographic techniques. Ho...
Binary attestation, as proposed by the Trusted Computing Group (TCG), is a pragmatic approach for software integrity protection and verification. However, it has also various sho...
In this paper, we present a novel distributed certification system in which signing a certificate needs the collaboration of a fixed ratio of the nodes, hence a varying number of n...
We present a non-malleable commitment scheme that retains its security properties even when concurrently executed a polynomial number of times. That is, a manin-the-middle adversa...
In this work, we study the security of public WLAN-based positioning systems. Specifically, we investigate the Skyhook positioning system, available on PCs and used on a number of...
