MI: Cross-layer Malleable Identity

Abstract-Access to Internet services is granted based on application-layer user identities, which also offer accountability. The revered layered network model dictates a disparate networklayer identity scheme for systems. We challenge this religious layered model adherence by demonstrating the practical benefits derived from a cross-layer identity scheme. Instead of a rigid identity, our malleable identity (MI) scheme empowers a traffic originator to fine-tune, on a per-case basis if necessary, her 3rd-party issued identity attributes embedded in an identity voucher (IV). When tagged to traffic, IVs benefit users, the Internet and services. A user can (a) control her traffic identifiability, ranging from anonymous, pseudonymous to personallyidentifiable through attributes fine-tuning and (b) enjoy Internetwide Single-Sign On (SSO) to network-layer Internet resources and application-layer services through IV persistence, without privacy loss naturally associated with SSO. The Internet and services can prioritize traffic, using IV attributes, as defense against Denial-of-Capability (DoC), Distributed Denial-of-Service (DDoS) and Border Gateway Protocol (BGP) prefix hijack/route forgery. MI is protocol/architecture-agnostic, and backwards/forwards compatible

Cybex: The cybersecurity information exchange framework (x.1500

ABSTRACT The cybersecurity information exchange framework, known as CYBEX, is currently undergoing its first iteration of standardization efforts within ITU-T. The framework describes how cybersecurity information is exchanged between cybersecurity entities on a global scale and how the exchange is assured. The worldwide implementation of the framework will eventually minimize the disparate availability of cybersecurity information. This paper provides a specification overview, use cases, and the current status of CYBEX

High-speed and handover-free communications for high-speed trains using switched WDM fiber-wireless system

A high-speed, handover-free communication for high-speed trains by a switched WDM fiber-wireless system in the W-band is presented. More than 20 Gb/s signal transmission with a cell switching time of less than 4 μs is experimentally demonstrated

Space QUEST mission proposal: experimentally testing decoherence due to gravity

Models of quantum systems on curved space-times lack sufficient experimental verification. Some speculative theories suggest that quantum correlations, such as entanglement, may exhibit different behavior to purely classical correlations in curved space. By measuring this effect or lack thereof, we can test the hypotheses behind several such models. For instance, as predicted by Ralph et al [5] and Ralph and Pienaar [1], a bipartite entangled system could decohere if each particle traversed through a different gravitational field gradient. We propose to study this effect in a ground to space uplink scenario. We extend the above theoretical predictions of Ralph and coworkers and discuss the scientific consequences of detecting/failing to detect the predicted gravitational decoherence. We present a detailed mission design of the European Space Agency's Space QUEST (Space—Quantum Entanglement Space Test) mission, and study the feasibility of the mission scheme.© 2018 The Author(s
