ECDSA and DNSSEC
ECDSA and DNSSEC
Geoff Huston — Nov 11, 2014 09:35 AM

Yes, that's a cryptic topic, even for an article that addresses matters of the use of cryptographic algorithms, so congratulations for getting even this far! This is a report of an experiment conducted in September and October 2014 by the authors to measure the extent to which deployed DNSSEC-validating resolvers fully support the use of the Elliptic Curve Digital Signature Algorithm (ECDSA) with curve P-256.

Privacy and Security - Five Objectives
Geoff Huston — Nov 06, 2014 10:50 AM

It has been a very busy period in the domain of computer security. With "shellshock", "heartbleed" and NTP monlink adding to the background of open DNS resolvers, port 445 viral nasties, SYN attacks and other forms of vulnerability exploits, it's getting very hard to see the forest for the trees. We are spending large amounts of resources in reacting to various vulnerabilities and attempting to mitigate individual network attacks, but are we making overall progress? What activities would constitute "progress" anyway?

Data Streaming in RIPE Atlas
Data Streaming in RIPE Atlas
Suzanne Taylor Muzzin — Oct 31, 2014 01:35 PM

RIPE Atlas data is now available as a live data stream, opening the door to a host of new applications and use cases. Learn more about how this powerful new functionality can benefit your network.

Secure Internet Routing with RPKI
Secure Internet Routing with RPKI
Remy de Boer — Oct 30, 2014 04:15 PM

Last week we improved the security of our routing infrastructure by implementing RPKI (Resource Public Key Infrastructure), a technology that can be used to secure the Internet routing infrastructure. RPKI was the topic of my Master's thesis and in this article I am trying to convince you to use this important technology for a more secure Internet.

Experiment Proposal to Improve K-root
Experiment Proposal to Improve K-root
Suzanne Taylor Muzzin — Oct 29, 2014 05:15 PM

We used RIPE Atlas to measure latency times to K-root, and we believe we can improve those times by adding new nodes to K-root in strategic locations. Here, we propose the idea of developing an experiment that would let us measure this potential improvement.

RIPE Atlas: New Measurements UI and Tagging
RIPE Atlas: New Measurements UI and Tagging
Suzanne Taylor Muzzin — Oct 28, 2014 10:30 AM

We're very excited to announce an all-new user interface (UI) for RIPE Atlas measurements. Users can now schedule, monitor and manage their own customised measurements more efficiently than ever before, and can now make use of the tagging feature when selecting probes for use in those measurements. Learn more about the new features below, explore the new interface, and let us know what you think.

RIPE Atlas Value Proposition
Suzanne Taylor Muzzin — Oct 24, 2014 02:50 PM

During its meeting in September, the RIPE NCC presented the RIPE NCC Executive Board with a value proposition document detailing the value that RIPE Atlas can bring to network operators, researchers and the Internet community as a whole. The board asked the RIPE NCC to publish this document, which we have done here. We also plan to incorporate much of its content into the RIPE Atlas website so that RIPE Atlas users can clearly understand the different ways this global Internet measurement network can be used and the many unique benefits it provides.

LISPmob: a Flexible LISP Implementation
LISPmob: a Flexible LISP Implementation
Alberto Rodriguez-Natal — Oct 22, 2014 02:55 PM

The Locator/ID Separation Protocol (LISP) decouples identity from location on the current IP addresses by creating two separate namespaces. The LISPmob project aims to bring a full-featured LISP open-source implementation to Linux-flavoured systems.

Building The Next Generation RIS Route Collectors
Building The Next Generation RIS Route Collectors
Wouter Miltenburg — Oct 20, 2014 11:20 AM

This is the second part of a research project investigating the possible replacement of the current Remote Route Collectors (RRC) used for the Routing Information Services (RIS). In the second phase we developed a prototype based on the requirements determined in the first phase. Both parts of this research project were done as part of my bachelor thesis at the Hogeschool van Amsterdam (HvA).

Data Acquisition Networks for Large Experiments
Data Acquisition Networks for Large Experiments
Grzegorz Jereczek — Oct 16, 2014 04:15 PM

The ATLAS, CMS, ALICE and LHCb particle detectors are designed to study particle collisions at the Large Hadron Collider (LHC) at CERN. Those as well as other existing and emerging large-scale experiments produce increasingly high volumes of data. Their source can be a wide variety of instruments, including sensors, detectors, antennas or telescopes. Although characteristics and goals of these experiments vary, they share a common challenge for real-time filtering, storage and analysis of the acquired data. One of the key components of this chain is a network, called the data acquisition network (DAQ).
