The APNIC Blog has recently published a very interesting article by Willem Toorop of NLnet Labs on the relationship between Security Extensions for the DNS (DNSSEC) and DNS over Transport Layer Security. Willem is probably being deliberately provocative in claiming that “DoT could realistically become a viable replacement for DNSSEC.”…
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…
The period around the end of the nineteenth century and the start of the twentieth century saw a number of phenomenal advances in the physical sciences. There was J.J. Thompson’s discovery of the electron in 1897, Max Planck’s quantum hypothesis in 1900, Einstein’s ground-breaking papers on Brownian motion, the photoelectric…
The Problem It’s pretty clear that the Internet has a problem. If you want to include Facebook’s misuse of personal information in ways that closely resemble unconstrained abandon, then the Internet probably has hundreds of millions of problems! More prosaically, lets confine our view of problems to the Internet Protocol…
In September 2017 the proposed roll of the Root Zone Key Signing Key (KSK), scheduled for 11th October 2017 was suspended. I wrote about the reasons for this suspension of the key roll at the time. The grounds for this action was based in the early analysis of data derived…
“Bikeshedding” Parkinson’s Law of Triviality is C. Northcote Parkinson’s 1957 argument that members of an organisation give disproportionate weight to trivial issues. He provides the example of a fictional committee whose job was to approve the plans for a nuclear power plant. He postulates that they would spend the majority…
APNIC Labs is partnering with Cloudflare for a joint research project relating to the operation of the DNS. I’d like to explain our motivation in entering into this research project, explain what we hope to be able to achieve with this work, and describe briefly how we intend to handle…
March has seen the first of the DNS Operations, Analysis, and Research Center (OARC) workshops for the year, where two days where too much DNS is just not enough! These workshops are a concentrated two days of presentations and discussions that focus exclusively in the current state of the DNS.…
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…
In this final article of a trio that looks at today’s “hot” topics in the DNS, I’d like to look at ways that recursive resolvers in the DNS can take some further steps that assist other parts of the DNS, notably the set of authoritative name servers, including root zone…
