    Security of Two-Way Quantum Key Distribution

    Quantum key distribution protocols typically make use of a one-way quantum channel to distribute a shared secret string to two distant users. However, protocols exploiting a two-way quantum channel have been proposed as an alternative route to the same goal, with the potential advantage of outperforming one-way protocols. Here, the...

    Error and Attack Vulnerability of Temporal Networks

    The study of real-world communication systems via complex network models has greatly expanded the people understanding on how information flows, even in completely decentralized architectures such as mobile wireless networks. Nonetheless, static network models cannot capture the time-varying aspects and, therefore, various temporal metrics have been introduced. In this paper,...

    The Seven Deadly Sins of Cloud Computing Research

    Research into distributed parallelism on "The cloud" has surged lately. As the research agenda and methodology in this area are being established, the authors observe a tendency towards certain common simplifications and shortcuts employed by researchers, which they provocatively term "Sins". They believe that these sins, in some cases, are...

    STOP: Socio-Temporal Opportunistic Patching of Short Range Mobile Malware

    Mobile phones are integral to everyday life with emails, social networking, online banking and other applications; however, the wealth of private information accessible increases economic incentives for attackers. Compared with fixed networks, mobile malware can replicate through both long range messaging and short range radio technologies; the former can be...

    CHERI: A Research Platform Deconflating Hardware Virtualization and Protection

    Contemporary CPU architectures conflate virtualization and protection, imposing virtualization-related performance, programmability, and debuggability penalties on software requiring fine-grained protection. First observed in micro-kernel research, these problems are increasingly apparent in recent attempts to mitigate software vulnerabilities through application compartmentalisation. Capability Hardware Enhanced RISC Instructions (CHERI) extend RISC ISAs to support...
