Video: Data Protection Day: "After Snowden: using law and technology to counter snooping"

On the occasion of Data Protection Day, Pieter Omtzigt invited Jacob Appelbaum, Douwe Korff and Christian Grothoff to testify on "using law and technology to counter snooping" at the Counsil of Europe (CoE). Peter Omtzigt is rapporteur for a report on "Massive eavesdropping in Europe".

Video: 30c3 talk on "The GNU Name System"

Here is the video of my talk (with help from Florian Dold) at 30c3 on "The GNU Name System". Sadly, the "Secure Name Systems" panel at the same venue was not recorded.

Typo-Protected Public Keys

When users type in public keys (such as the 53-characters of a GNS zone), they might make typos. The usual way to fix typos is to add a checksum, further increasing the length of the sequence that has to be typed in.

Join GNS Key Exchange Party at 30C3 Hamburg

The GNU Name System (aka GNS) is a fully decentralized, censorship resistant naming system based on the idea of a pet name system not relying on centralized organizations. Every user manages his own namespace. To access names and records of other user's you have to exchange some specific information which can be done in a convinient way using a business card with a QR code containing your GNS information.

GNUnet 0.10.0

Source Code (TGZ)

We are pleased to announce the release of GNUnet 0.10.0. This release represents a major overhaul of the cryptographic primitives used by the system. GNUnet used RSA 2048 since its inception in 2001, but as of GNUnet 0.10.0, we are "powered by Curve25519". Naturally, changing cryptographic primitives like this breaks backwards compatibility entirely. We have used this opportunity to implement protocol improvements all over the system.

Knock: Practical and Secure Stealthy Servers

Knock is a kernel patch that implements a new NAT-compatible TCP option for stealthy port knocking with a few new twists for improved security which is referred to as TCP Stealth.

Developer Documentation of the Week: The GNU Name System

I've just finished an update of the developer handbook chapter on the GNU Name System (GNS). GNS is used as the public key infrastructure (PKI) for GNUnet (and hopefully other applications). GNS names are structured like DNS names and GNS can be used as an alternative to DNS, as common record types from DNS are supported in DNS.
