YBTI @32C3

December 7th, 2015 No comments

youbroketheman There will be a “You broke the internet” / We fix the net” assembly @32C3 organised by GnuNet.

Currently it takes enthusiasts to fill in the gaps between what researchers and companies have released and turn it into something that actually works for the population. We think we need incentives to polish the protocol stack of a GNU Internet, and by GNU we mean that the involved software needs to be free as in free speech, and that we need regulation to actually deploy an upgrade of the Internet to a version that protects its participants from eavesdropping and social correlation.

Kerckhoffs’s principle

November 2nd, 2015 No comments

“The security of a cryptosystem should depend solely on the secrecy of the key and the private randomizer, not of the secrecy of the used cryptographic algorithm.”

AliceBobCryptoExample

“Un grand nombre de combinaisons ingénieuses peuvent répondre au but qu’on veut atteindre dans le premier cas ; dans le second, il faut un système remplissant certaines conditions exceptionnelles, conditions que je résumerai sous les six chefs suivants:

1° Le système doit être matériellement, sinon mathématiquement, indéchiffrable

2° Il faut qu’il n’exige pas le secret, et qu’il puisse sans inconvénient tomber entre les mains de l’ennemi

3° La clef doit pouvoir en être communiquée et retenue sans le secours de notes écrites, et être changée ou modifiée au gré des correspondants

4° Il faut qu’il soit applicable à la correspondance télégraphique

5° Il faut qu’il soit portatif, et que son maniement ou son fonctionnement n’exige pas le concours de plusieurs personnes

6° Enfin, il est nécessaire, vu les circonstances qui en commandent l’application, que le système soit d’un usage facile, ne demandant ni tension d’esprit, ni la connaissance d’une longue série de règles à observer.

Tout le monde est d’accord pour admettre la raison d’être des trois derniers desiderata ; on ne l’est plus, lorsqu’il s’agit des trois premiers.”

ex “La cryptographie militaire” Auguste Kerckhoffs, janvier 1883

23 years of Linux

August 25th, 2014 No comments

Congratulations, Linus Torvalds, and thanks for inventing and writing the GNU/Linux Kernel since 23(!) years!

Hello everybody out there using minix –

I’m doing a (free) operating system (just a hobby, won’t be big and
professional like gnu) for 386(486) AT clones. This has been brewing
since april, and is starting to get ready. I’d like any feedback on
things people like/dislike in minix, as my OS resembles it somewhat
(same physical layout of the file-system (due to practical reasons)
among other things).

I’ve currently ported bash(1.08) and gcc(1.40), and things seem to work.
This implies that I’ll get something practical within a few months, and
I’d like to know what features most people would want. Any suggestions
are welcome, but I won’t promise I’ll implement them 🙂

Linus (torv…@kruuna.helsinki.fi)

PS. Yes – it’s free of any minix code, and it has a multi-threaded fs.
It is NOT protable (uses 386 task switching etc), and it probably never
will support anything other than AT-harddisks, as that’s all I have :-(.

CCC proudly announces honorary members Chelsea Manning and Edward Snowden

Congratulations, CCC!

Chaos Computer Club supports Chelsea Manning and Edward Snowden
2014-08-24 00:52:00, 46halbe

Since its founding more than thirty years ago, the Chaos Computer Club (CCC) holds strong beliefs in the freedom of information. Consequentially, freedom fighters and whistleblowers deserve our utmost respect and support. For this reason we will help the European legal team of Edward Snowden financially.

Asylum, legal counsel and protection are costly. This is why we decided to support Snowden’s six European lawyers with 36.000 Euro to cover their expenses. Earlier this year, the CCC general assembly also decided to offer Edward Snowden the honorary membership, which he accepted gladly.

“The long lasting dedication of the CCC and others for citizen’s rights and against mass surveillance paved the road for a broad public debate after Edward Snowden’s revelations”, said Snowden’s German lawyer, Wolfgang Kaleck. “Both the commitment as well as the support for Snowden require perseverance. The financial support provided will help sustain these efforts.”

Edward Snowden is the source of many leaks about the so-called Intelligence Community and their hacking and surveillance operations, which made news headlines all over the world. He ignited the necessary global discussion by informing journalists about how much and how deeply we are being spied on by the NSA and their partners, how they infiltrate telecommunication and Internet service providers. One of our central claims and part of our hacker ethics is: “Public data should be utilized, private data should be protected.” Edward Snowden had the guts to live by our principles.

Undoubtedly, Chelsea Manning’s courageous actions also stand in line with these values of ours. To express our support and respect, the CCC bi-annual general assembly unanimously voted for offering her the honorary membership. She agreed to accept our offer. Needless to say, it is an outstanding honor for us to count Chelsea Manning as one of us!

The former US private Chelsea Manning, stationed in Iraq in 2009 and 2010, was sentenced for violations of the Espionage Act and other offences in August 2013. Allegedly, she transferred hundreds of thousands of military and U.S. State Department documents and the infamous “collateral murder” video to Wikileaks. Detained as a political prisoner in 2010 under unduly harsh conditions without minimal standards of humane treatment and stripped of her clothing in custody every night, Manning is now serving a 35-year sentence for her courageous acts.
