Crypto Talk at 27C3: New Key Recovery Attacks on RC4/WEP, Day 4, 17:15, Saal 2

EN

The RC4 Stream Cipher could be the most common stream cipher used on the Internet. RC4 is the only Stream Cipher which is standardized for the SSL/TLS protocol, it is also used for WEP and WPA protected wireless networks. Initially, RC4 was designed to be a closed source commercial product, with the core algorithm kept secret. In 1994, the source code for RC4 was posted on the internet and the algorithm could be analyzed.

The first attack on RC4 was published by Fluhrer, Mantin, and Shamir in 2001. The attack is very effective, but can only be used against certain keys starting with a special …

i3 is a tiling window manager, that means it configures your windows to use the whole available screen space. It was written from scratch with focus on clear and well-documented code. Additionally, a lot of documentation like the User’s Guide or a Hacking Howto is available. i3 is fast, easy to use and configure, features full unicode and decent multi-monitor support.

Two of the core developers are traditionally attending the Chaos Communication Congress and are in the hackcenter (the 4-person table in the middle of the hackcenter, watch out for the i3 poster), ready to answer your questions, …

Crypto Talk at 27C3: FrozenCache – Mitigating cold-boot attacks for Full-Disk-Encryption software, Day 3, 23:00, Saal 2

EN

Cold BootsAs a general attack against encryption software on a computer, the cold boot attack was presented at 25C3. To encrypt data on a PC, many programs store the encryption key in RAM. The key is usually derived from a password or loaded from the hard disk where it is protected by a password too. The key resists as least as long as the encryption operation take in RAM. For many applications like Full-Disk-Encryption or Email Signatures, it is convenient to keep the key permanently in RAM, once it has been loaded, so that the user doesn’t need to enter his password again and again.

To protect the key …

Speaking of: Intercensor – Internet Censorship Game

EN

In the past years there was a lot of discussion about internet censorship. To get an actual impression of how censorship may be implemented and what methods of circumvention are possible, we created the Intercensor Project. Your task is to bring your laptop, connect it to our special switch and choose a challenge to solve. We provide several levels of difficulty and various methods of censorship, so that you can play around with many ways of circumvention.

We invite you to visit our table at the Hackcenter (in the back, near the elevator), try the game and give us feedback.

Let’s encrypt and authenticate the whole internet.

EN

An average internet user who has to deal with cryptography: big problem. An average programmer who has to secure his protocol with cryptography: a much bigger problem. Practically, because not every programmer cares much about cryptography. Theoretically, because it is sort of a bad design if everyone implements it in their own piece of software.

Last year, fefe and erdgeist showed impressively how hard it is for a programmer to create a socket, let alone open a connection to another machine on the Internet. Today, as a programmer, you also have to encrypt your connection; you have to …

Crypto Talk at 27C3: High-speed high-security cryptography: encrypting and authenticating the whole Internet, Day 2, 20:30, Saal 1

EN

High SpeedAs many of us know, the whole internet should be regarded as an insecure place. At every place where your internet traffic passes by, it can be modified, suppressed or recorded. Daniel J. Bernstein will show us how you can prevent this from happening:

This talk will present a different approach to high-security Internet cryptography. This approach is easy for users, easy for system administrators, and, perhaps most importantly, easy for programmers. The main reason that the approach has not been tried before is that it seems to involve very slow cryptographic operations; this talk will show …

Today at 18:30: The concert in Saal 1.

This morning, a concert grand (see photo) was delivered to the stage of Saal one for a special event today: Starting at 18:30 hrs, Corey Cerovsek, Alex Antener and Julien Quentin will be giving a classical concert.

They will be playing pieces from many different composers, including Lennon, Bernstein (Leonard probably; Dan Bernstein can be heard one hour later in the same Saal ;-), Mozart, Liszt and Paganini, to name a few. But there’s more:

In this very concert copyright and public domain issues will be discussed—and a (musical) answer will be given: what would classical music sound like if …

Crypto Talk at 27C3: Is the SSLiverse a safe place? Day 2, 16:00, Saal 2

EN

SSL/TLS is the standard when it comes to securing HTTP traffic on the internet. The authenticity of a web server is usually secured using a X.509 certificate digitally signed by a trusted certification authority (CA). All major web browsers come with a list of CAs preinstalled they assume as trustworthy. Every website can be signed by any of these CAs, so no web browser would show a warning, if www.dod.gov would be signed by a Chinese certification authority or the Deutsche Telekom.

ObservatoryTo examine the usage of X.509 certificates for SSL/TLS, the EFF installed a SSL Observatory:

Crypto Talk at 27C3: Die gesamte Technik ist sicher, Day 1, 21:45, Saal 1

EN

NPAThe new national id card Neuer Personalausweis (NPA) was one of the biggest IT projects in the German government in the last years. Compared to the old id card, the new id card is a RFID smart card, which can also be used on the internet to prove your identify to a remote party (Ebay, Paypal, or Amazon for example) and to sign binding contracts. For example, you can use the card to buy a new house or car, or open up a bank account or apply for a credit.

When using the card over the internet, the card is connected to a reader, which is connected to a (potentially insecure) PC, which is …

Crypto Talk at 27C3: Automatic Identification of Cryptographic Primitives in Software, Day1, 16:00, Saal 3

EN

FingerprintMany applications, including closed source applications like malware or DRM-enabled multimedia players (you might consider them as malware too) use cryptography. When analyzing these applications, a first step is the identification and localization of the cryptographic building blocks (cryptographic primitives, for example AES, DES, RSA…) in the applications. When these blocks have been localized, the input and output of the cryptographic primitives and the key management can be observed and the application can be analyzed further. Fortunately, many cryptographic algorithms use special …

Change of Plan — Video Streams For Peace Missions

In one of our last posts we’ve invited all peace missions to register their IP addresses by mail. Registered IP addresses will be granted access to a dedicated video streaming relay.

We’ve received mails from lots of people, who’d like to set up a peace mission and gave us their IP address. So far, so good – it’s cool to see so much interest. Unfortunately, now you’ve invested time for sending us an email, we do change the registration procedure.

There will be a web site, where peace missions can register. After we’ve acknowledged a registration you may add or change your IP address on the …

Workshops

EN

During all the years there were really great workshops at the Chaos Communication Congress. Unfortunately they were a bit hard to find, because we only announced them in the wiki and some workshops weren’t in there either. So it is clear, that the lack of attendees in some workshops was surely not because of uninteresting topics but merely because of our laziness to make them easier to find.

Our approach to that problem is to ask all visitors who want to give a workshop at 27C3 to hand it in before the conference so we can release an official schedule for workshops before day 1 of the …

All group orders that have been requested by now can still buy their tickets, but we won’t raise the ticket limit for any more accounts. Thanks for your understanding.
