The Problem With HTTPS SSL Runs Deeper Than MD5

The recent research highlighting the alarming practice of Secure Socket Layer (SSL) Certificate Authority (CA) vendors using the MD5 hashing algorithm (which was known to be broken since 2005) has shown a major crack in the foundation of the Web. While the latest research has shown that fake SSL certificates with MD5 hashes can be forged to perfection when the CA (such as VeriSign's RapidSSL) uses predictable certificate fields, the bigger problem is that the web has fundamentally botched secure authentication. more

Why DNS is Broken, in Plain English

At ICANN's meeting in Egypt last week, I had the opportunity to try and explain to various non-technical audiences why the Domain Name System (DNS) is vulnerable to attack, and why that is important, without needing a computer science degree to understand it. Here is the summary. more

Proposal for Signing the DNSSEC Root

The U.S. National Telecommunications and Information Administration (NTIA) is soliciting comments on signing the DNSSEC root. Ignore the caption on the page: this is not about DNSSEC deployment, which is already happening just fine. It's about who gets to sign the root zone. more

DNSSEC Rally

In late August the White House mandated that all of the agencies in the US government have functioning DNSSEC capabilities deployed and operational by December 2009. I am suggesting here that we, as a community, commit to the same timetable. I call upon VeriSign and other registries to bring up DNSSEC support by January 2009. more

Trust, but Verify

We are at an inflection point in our lifetimes. The Internet is broken, seriously broken... Almost all of the systems currently in use on the Internet are based on implicit trust. This has to change. The problem is that these systems are so embedded in our everyday lives that it would be, sort of like, changing gravity, very difficult. more

Is This Only Sloppy Wording by ICANN?

So I wrote earlier that I though it was good stuff when ICANN released a paper on DNS Security. Yes, I think it was good this paper was released, and yes it points out correctly how important DNSSEC is. But, now when reading it in detail, I find two things that troubles me. And it has to do with management of .ARPA. A top level domain that is used for infrastructural purposes. Like IP-addresses and E.164 numbers... more

ICANN Releases Paper on Domain Name Security

Today ICANN releases a paper with the title "DNSSEC @ ICANN - Signing the root zone: A way forward toward operational readiness". The paper explains in more detail than earlier documents what ICANN view on signing of the root zone is. I think the key points mentioned in this paper are true, and in general, I think this document is a good read. It is not long, and summarizes what I would call the current view is. more

An Astonishing Collaboration

Wow. It's out. It's finally, finally out... So there's a bug in DNS, the name-to-address mapping system at the core of most Internet services. DNS goes bad, every website goes bad, and every email goes...somewhere. Not where it was supposed to... I'm pretty proud of what we accomplished here. We got Windows. We got Cisco IOS. We got Nominum. We got BIND 9, and when we couldn't get BIND 8, we got Yahoo, the biggest BIND 8 deployment we knew of, to publicly commit to abandoning it entirely. It was a good day... more

Will a Global TAR Make DNSSEC Stick?

Two US Government contractors and the National Institute of Science and Technology have released a white paper, "Statement of Needed Internet Capability," detailing possible alternatives and considerations for a Trust Anchor Repository (TAR) to support DNSSEC deployment. The document was released through the DNSSEC-Deployment Group this week with a request that it be circulated as widely as possible to gather feedback. A Trust Anchor Repository (TAR) refers to the concept of a DNS resource record store that contains secure entry point keys... more
