The use of online social networks, such as Facebook and Twitter, has grown at a
phenomenal rate. These platforms offer services that support interactions via messaging …

Online social networks (OSNs) such as Facebook and Google+ have transformed the way
our society communicates. However, this success has come at the cost of user privacy; in …

Peer-to-peer computing and networking are important developments for large-scale
distributed systems design and the evolution of Internet architecture. Widely used …

Information-centric network architectures are an increasingly important approach for future
Internet architectures. Several approaches are based on a non-hierarchical identifier (ID) …

Resource location or discovery is a key issue for Grid systems in which applications are
composed of hardware and software resources that need to be located. Classical …

Information-centric network (ICN) architectures are an increasingly important approach for
the future Internet. Several ICN approaches are based on a flat object ID namespace and …

Distributed Hash Table (DHT) lookup is a core technique in structured peer-to-peer (P2P)
networks. Its decentralized nature introduces security and privacy vulnerabilities for …

Abstract Distributed Hash Tables (DHT) are presently used in several large-scale systems in
the Internet and envisaged as a key mechanism to provide identifier-locator separation for …

We study the problem of reliably searching for resources in untrusted peer-to-peer networks,
where a significant portion of the participating network nodes may act maliciously to subvert …

In this work, we study hierarchical DHT-based Peer-to-Peer (P2P) systems. We present an
analytical model for two-tier architectures deploying a DHT at the top-level overlay and …
