Call for Participation: Chaos Communication Camp 2019

Wed, 22 May 2019 14:19:24 +0000

The Chaos Communication Camp in Mildenberg is an open-air hacker camp and party that takes place every four years, organized by the Chaos Computer Club (CCC). Thousands of hackers, technology freaks, artists and utopians get together for five days in the Brandenburg summer – to communicate, learn, hack and party together.

We focus on topics such as information technology, digital security, hacking, crafting, making and breaking, and we engage in creative, sceptical discourse on the interaction between technology and society.

We’d love to see your submission for these tracks:

Arts & Culture,
Ethics, Society & Politics,
Hardware & Making,
Security & Hacking,
Science.

Apart from the official conference program on the main stages, the Chaos Communication Camp also offers space for community villages, developer and project meetings, art installations, lightning talks and numerous workshops (called “self-organized sessions”).

Lightning talks

Got something interesting to say but don’t want to submit a full talk? Consider doing a lightning talk instead! You will have five minutes to present your ideas or projects – or just to rant, if you need to vent. A formal submission through our submission system (called „frab“) is not required; as usual, the lightning talks are organized via our public wiki. Lightning talks can be held in German or English and will be streamed, recorded and published (see below).

For projects, installations, workshops, sessions hosted in assemblies and other fun stuff is no formal submission through frab required. There will be a wiki page to keep track of requirements for space and other resources. Simply start already considering now what you would like to make, bring, or show, and write it down once the wiki goes online.

Dates & deadlines

May 22th, 2019: Call for Participation
June 11th, 2019 (23:59 CEST): Deadline for submissions
July 10th: Notification of acceptance
August 21st – 25th, 2019: Chaos Communication Camp at Ziegeleipark Mildenberg

Submission guidelines for talks

All lectures need to be submitted to our conference planning system under the following URL: https://frab.cccv.de/cfp/camp2019.

Please follow the instructions there. If you have any questions regarding the submission, you are welcome to contact us via mail at camp2019-content@cccv.de.

Please send us a description of your suggested talk that is as complete as possible. The description is the central criteria for acceptance or rejection, so please ensure that it is as clear and complete as possible. Quality comes before quantity. Due to the non-commercial nature of the event, presentations which aim to market or promote commercial products or entities will be rejected without consideration.

Since most participants find – or don’t find a lecture by its title, it’s important to keep your talk description precise, accessible and comprehensible. Our teams will keep a keen eye on title and subtitle and make suggestions to change them if necessary, so please avoid insider jokes and stereotypes.

As it is likely that there will be multiple submissions on the same topic, please show us exactly why your talk should be part of the conference. Remember that the teams are diversely staffed, and not every reviewer knows every submitter and their backgrounds. Please write something about yourself, your research, and your motivation. It does not matter if the talk has been held at another conference somewhere on this planet, as long as it is up to date and relevant.

Talks should be 45 minutes long and can include up to 15 minutes for questions and answers. Longer slots are possible if absolutely necessary, but should be an exception. Please take our limited amount of presentation time into consideration, check how much time you really need to bring home your points and then tell us the proposed length of your talk.

Language

Although the Chaos Communication Camp is an international event and a lot of content is presented in English, there will again be a translation team that will simultaneously translate most German talks into English. So if you are not comfortable with presenting in English, don’t hesitate to present your lecture in German. If your talk will be held in English, your submission should also be in English.

Publication

Audio and video recordings of the lectures will be published in various formats at media.ccc.de under the license Creative Commons Attribution 4.0 International (CC BY 4.0). This license allows commercial use of excerpts by media institutions as part of their reporting. If you do not wish for material from your lecture to be published or streamed, please let us know in your submission.

Note: As German law (and therefore the license) might differ from the law of your country, please let us know if you have any issues or questions regarding the exact implications. Unfortunately, we can’t guarantee a perfect translation.

Travel, costs & visa

The Chaos Communication Camp is a great adventure for us, also financially. As we’re all there to have a nice time together, and split the costs, we cannot offer a different entrance fee for speakers, workshop organizers or angels. The camp is a non-commercial event where neither the organisers nor the speakers are being paid – thus, we cannot provide a free entrance ticket, even for speakers. If necessary, we are however able to provide limited support for travel costs.

If you need help applying for a visa, such as an official invitation to present to the German embassy, please let the content team know well in advance. Please be aware that the visa application procedure may take up to six weeks or longer!

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

Mon, 27 Dec 2010 01:31:51 +0000

Many 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 constants or have a typical fingerprint and there are only a few different public implementations of the algorithm. This allows us to automate this first, Felix Gröbert will show us how:

Using dynamic binary instrumentation, we record instructions of a program during runtime and create a fine-grained trace. We implement a trace analysis tool, which also provides methods to reconstruct high-level information from a trace, for example control flow graphs or loops, to detect cryptographic algorithms and their parameters.

Trace driven/dynamic analysis has some advantages of static analysis:

Because the program is analyzed at runtime, it is immediately known which parts of the code are used at which time, so that they might be correlated with runtime decryption of the code or with network communication.
Inputs and outputs of the primitives as well as the keys are recorded, even if the originate from a remote server or botnet. This allows us to immediately distinguish between long term keys and session keys, if multiple executions of the same program can be recorded.
This is also highly interesting if private keys are included in an obfuscated binary, for example private RSA keys.
Dead or unused code is automatically excluded, so that one can proceed with the main parts of the code first.
If additional code is loaded from a server, it is included in the analysis. This would be hard to impossible using static analysis.

Of course, trace driven analysis has it disadvantages, for example if a malware needs to communicate with a command-and-control server, which has already been taken down or behaves differently on different systems or at different times.__

Personally, I am interested in this talk because it might make ease up the analysis of closed source applications using cryptography. Even if the application, the DRM scheme, or the cryptographic primitive has no special weaknesses or bugs, just he recording of every input and output of all cryptographic building blocks in the application might be sufficient to extract a DRM free version of DRM protected digital content. Please also note that even if an application uses only well analyzed cryptographic primitives as AES and RSA, it might still be insecure, if these primitives are used in the wrong way.

See the talk at Day 1, 16:00, Saal 3!

Bring Your DVB-T receivers

Thu, 23 Dec 2010 00:31:56 +0000

At 27C3 all lectures will be broadcast via DVB-T and reception will be possible in and around the bcc. Visitors can watch via TV if they want avoid overcrowded lecture rooms.

To receive the signal any PC with DVB-T-USB-Stick, TV set with DVB-T tuner or cellphone with DVB-T-function will work. We will publish all needed configuration files and a list of working and non-working receivers in the wiki.

The Bundesnetzagentur (German regulation body) has allocated channel 22 (482MHz) for us, where we will transmit with 6 watts ERP.

The last time DVB-T was available on Chaos Congress was at 24C3 where in some areas the signal was to much attenuated to be received properly. This year we come up against this with more transmission power, better
placement of the transmitter antenna and a new, better modulator.

Details are available at http://events.ccc.de/congress/2010/wiki/DVB-T

24 Hour Hardware Hacking Returns to 27c3

Thu, 16 Dec 2010 19:54:29 +0000

Hackers of all ages can (learn how to) make things at the Hardware Hacking Area of the 27c3!

The HHA is open to everyone and open the entire congress! Hackers of all ages and skill levels are welcome! Round-the-clock hands on workshops will be led by lots of experienced teachers like Mitch Altman, Jimmie P. Rodgers, fbz, Wim Vandeputte and…you!

Learn to solder, then help teach others! Make cool things with electronics, design and print 3D models on the Makerbot, break RFID, or give your own workshop on the projects you’ve been hacking on this year. Last year there was a Cantenna workshop, a Mikrocopter workshop, and a GSM workshop among many others.

Lots of kits for you to make will be available including Brain Machines, TV-B-Gones, Trippy RGB Waves, Mignonette Games, LEDcubes, LOL shields, Atari Punk Consoles…and there’s always room for yours!

To accommodate all this hardware hacking goodness, the HHA will be twice the size it was during the 26c3, but still conveniently located near the Hackcenter.

Even if you don’t have a ticket to Congress, you can stop by the HHA with a Night Pass good from Midnight to 6 AM. Night passes are only €5 and will be sold shortly before midnight each day of the 27c3.

Lightning Talks at the 27c3

Mon, 13 Dec 2010 19:04:15 +0000

Want four minutes on stage at the 27c3? You can have it! Registration is now open for the Lightning Talk sessions at the 27c3.

Taking place at 12:45 in Saal 3 on Days 2, 3 and 4, these fast paced sessions are perfect for pitching new software or hardware projects, exploits, creative pranks or strange ideas you need to share with the world.

Lightning talks are also good for getting publicity for your workshop at the 27c3, or for recruiting people to join in on things like a high calorie flash mob.

In order to maximize the available time, registrations will be granted to presenters who submit their graphics (i.e. slides, background picture, contact info, etc.) in advance. Exceptions will be made very selectively on a case-by-case basis. Register soon, as we anticipate the available slots will go quickly. (Proposals started coming in a few minutes after we put up a draft of the wiki page!)

Read the Lightning Talks article on the 27c3 wiki for more information!

Content Meetings are over: Fahrplan released

Wed, 10 Nov 2010 22:46:04 +0000

This past Sunday, we concluded the second and final Content Meeting for 27C3. We’ve looked at all 223 submissions for talks and presentations and selected what we feel are the best 98 of them. We’d like to thank all submitters for the many interesting proposals that lightened up our work.

One card for each talk that was accepted for 27C3

But now, the schedule for the 27th Chaos Communication Congress is mostly done. So today we present the first release of the 27C3 presentation schedule (or “Fahrplan” in German): Fahrplan Version 0.1. Note this is Version 0.1. Blanks will be filled with more really cool stuff. Much more to come.

The Content Team is shuffling cards on the floor to plan 27C3

This year we’ll also have talks that last 30 minutes. The intent is to create a space for issues that are too complex for a Lightning Talk but still would not fill an entire hour. The resulting increase in the number of presentations serves to diversify the programme as well as allow people to tune into the event with morning sessions that don’t require quite the same attention span we might be able to more easily muster in afternoons and evenings.

Finished schedule for 27C3

We will be highlighting some of the accepted talks with short introductions here soon. So stay tuned. :-)

Dear Speakers & Lightning-talkers

Sat, 13 Dec 2008 18:14:02 +0000

It’s time to glam up your lecture-descriptions!

Starting this year, every lecture’s long description will be printed in the Congress’ Proceedings. This was decided in the very last days.
So please try to enhance the abstract and description of your lecture in the particular Pentabarf-Record until:

Tomorrow, Sunday, 17:23:42 UTC

(9am PST; 12pm EST; 20pm MSK // 1am CNST; 3am AEST)

The long-description may even be one or two pages long, especially if you don’t submit a paper. Even your short-bio and, if given, a public photo will be printed.

If you are about to make a lightning-talk about your project, please fulfill the description and contact information on your talk in the wiki-page.
