Proof-of-work (PoW) is an algorithmic tool used to secure networks by imposing a
computational cost on participating devices. Unfortunately, traditional PoW schemes require …

Network coordinate (NC) systems provide a lightweight and scalable way for predicting the
distances, ie, round-trip latencies among Internet hosts. Most existing NC systems embed …

The performance of an anonymous path can be described using many network metrics–eg,
bandwidth, latency, jitter, loss, etc. However, existing relay selection algorithms have …

A network coordinate system assigns Euclidean “virtual” coordinates to every node in a
network to allow easy estimation of network latency between pairs of nodes that have never …

We argue that cyber-physical systems cannot be protected just by protecting their IT
infrastructure and that the CIA approach to security is insufficient. Rather, the IT components …

A network coordinate system assigns Euclidean “virtual” coordinates to every node in a
network to allow easy estimation of network latency between pairs of nodes that have never …

This paper presents the design and implementation of Application-Aware Anonymity (A³), an
extensible platform for deploying anonymity-based services on the Internet. A³ allows …

The canonical IT security properties are geared towards infrastructure security. The task of
an infrastructure security service is completed once data has been delivered to the …

A common tool to defend against Sybil attacks is proof-of-work, whereby computational
puzzles are used to limit the number of Sybil participants. Unfortunately, current Sybil …

Web3 is emerging as the new Internet-interaction model that facilitates direct collaboration
between strangers without a need for prior trust between network participants and without …
