Measuring ECDSA in DNSSEC – A Final Report

Back in 2014 I wrote on the use of the elliptical curve cryptographic algorithm in generating digital signatures for securing the DNS (DNSSEC). The conclusion at the time was hardly encouraging: “Will ECDSA ever be a useful tool for DNS and DNSSEC? As good as ECDSA is in presenting strong…


An Update on Securing BGP from IETF 102

One way or another we’ve been working on various aspects of securing the Internet’s inter-domain routing system for many years. I recall presentations dating back to the late ’90’s that point vaguely to using some form of digital signature on BGP updates that would allow a BGP speaker to assure…


Crypto Zealots

I’ve been prompted to write this brief opinion piece in response to a recent article posted on CircleID by Tony Rutkowski, where he characterises the IETF as a collection of “crypto zealots”. He offers the view that the IETF is behaving irresponsibly in attempting to place as much of the…


Peak DNSSEC?

The story about securing the DNS has a rich and, in Internet terms, protracted history. The original problem statement was simple: how can you tell if the answer you get from your query to the DNS system is ‘genuine’ or not? The DNS alone can’t help here. You ask a…


Ripe 75

RIPE held its 75th meeting in Dubai in mid-October. As usual there was a diverse set of presentations covering a broad range of activities that are taking place on today’s Internet. The topics include issues relating to network operations, regulatory policies, peering and interconnection, communications practices within data centres, IPv6,…


Not Rolling the KSK

For some years now (and it has definitely been two years, probably three and maybe longer) we have been working on a process of changing the cryptographic key that signs the Root Zone of the DNS. I wrote about this back in March 2016, describing both the role of this…


RIPE 74

RIPE 74 was held in May in Budapest, and as usual it was a meeting that mixed a diverse set of conversations and topics into a very busy week. Here are my impressions of the meeting drawn from a number of presentations that I found to be of personal interest.…


NANOG 69

NANOG 69 was held in Washington DC in early February. Here’s my notes from the meeting. It would not be Washington without a keynote opening talk about the broader political landscape and NANOG certainly ticked this box with a talk on international politics and cyberspace. I did learn a new…


Let’s Encrypt with DANE

There is a frequently quoted adage in communications that goes along the lines of “Good, Fast, Cheap: pick any two!” It may well be applied to many other forms of service design and delivery, but the basic idea is that high quality, high speed services are costly to obtain, and…


DNS DDOS

The recent attacks on the DNS infrastructure operated by DYN in October 2016 have generated a lot of comment in recent days. Indeed, it’s not often that the DNS itself has been prominent in the mainstream of news commentary, and in some ways this DNS DDOS prominence is for all…
