In 1994, the source code for RC4 was posted on the internet and the algorithm could be analyzed.

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.

EN

Day0 - II

Thanks to the Mission Angels, you’ll be able to interact with the talks going on at the 27c3 and more! While you watch the streams from one of many Peace Missions throughout the world, Mission Angels will be monitoring IRC and Twitter for questions to be asked in selected events during the 27c3.

To ask a question in a session on IRC join #27c3-Saal-1, #27c3-Saal-2, #27c3-Saal-3 on Freenode or use the corresponding terms as a Twitter hashtag to put your question to the session.

If you’re in a Peace Mission, you can even sign up to give a Lightning Talk!

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 …

We wish you a very merry festival of fixing the WiFi at your family’s home!

Over the past few days, the 27c3 team has been hard at work with the initial preparations for the 27c3.  At the bcc, several tons of networking hardware have arrived, the network backbone is up and running and the hackcenter decor is taking shape.  In far away lands, many new Peace Missions have been announced and there’s always room for more.

Peaceful journeys!  We’ll see you on the 27th!

No more group orders available

EN DE

We already got requests for 403 group tickets in 38 different orders. The majority are groups from foreign countries which want to visit the 27C3. We are really pleased to welcome you to the Congress!

On the other hand these group orders decrease the number of available tickets for individual visitors. Thus we concluded to end the group orders now. 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.

Performance test successfully survived!

EN DE

As expected, the pre-sale-system has survived the performance check immediately to the release time.

The rush for the Pre-sale is still enormously. The tickets from the first Quota will be sold out in no time.

But: No Panic.

As announced, there will be a second, much larger, quota at the beginning of November. So anyone who had no luck this time get a new chance at the second quota.

The created accounts are also valid in the second quota.

The quota for our volunteers (Angels) from last year, dubbed ‘the golden token’, will be independent of the other “normal” quota.

For all risks and side …

How to survive the pre-sale

EN DE

In order to avoid any confusion, here is the short and sweet version of everything there is to know about the 27C3 ticket presale.

  • The System will be available by today (10.10.10) at exactly 10:10am Berlin Time (08:10 UTC) via https://presale.events.ccc.de/ – if this doesn’t work, try https://213.73.91.79/ instead.
  • The first batch of 800 Tickets will be accessible by then. The second (and biggest) batch will start after we released the first version of the schedule (the Fahrplan) in the beginning of November. More batches will be announced after those. Everyone who did not get one of the …

ICE 2342 to 27c3 will be delayed by a few days.

EN DE

As may you have noticed, the start of ticket sales for the 27th Chaos Communication Congress is still delayed.

We understand your annoyance. Rest assured, it annoys us just as much.

Anyone of you ever involved in a project knows: Something always comes amiss, there is always some unexpected problem pushing the release date back into the future. Project “27c3” unfortunately is not an exception to this. Especially since all the work – including the presale system – is being done by volunteers, most of them with a regular day job.

Behind the scenes our coding and hacking mill is spinning, while …

Tickets for the 27th Chaos Communication Congress

EN DE

While the Call of Participation for the 27. Chaos Communication Congress (27C3) “We come in peace” lasts until 9th October 2010, we would like to make the travel scheduling for the willing people a bit easier. This year a Presale will be available.

Anticipation
Like it was impressively shown last year, the fluctuations in the rush on the Congress aren’t measurable in any way.
The bcc was completely packed, and all tickets sold. The principle of hope didn’t work out, and the displeasure by the people which traveled far and got rejected, or didn’t get a clear announcement relating to the …
