Lightning Talks are short lectures (almost) any congress participant may give!
Bring your infectious enthusiasm to an audience with a short attention span! Discuss a program, system or technique! Pitch your projects and ideas or try to rally a crew of people to your party or assembly! Whatever you bring, make it quick!

The Lightning Talks at the 30c3 were the best yet! We need your help to make them even better next year. Please e-mail to get in touch with the coordinators who put together next year's session.

Hacking With Care Emily EN Hacking (with) care is a versatile, collaborative initiative which purpose is to bring balance, embodiment, body & soul awareness and care to the hackers' communities, living by the shared ethics of goodness for all, joyful creativity, freedom and sharing of knowledge.

Hacking (with) care explores questions relative to hackers' psychological and physical well-being and health, and looks at how a sense of freedom in the technological realms can relate to a sense of freedom in one's life. We seek to encourage vitality and (data)love potentialities to blossom both on and away from keyboards. We also feel we want to return the favor to those who, often behind their computers, care for all of us by engaging everyday in straining battles for freedom.

Wir werden alle überwacht. Und nun? Mspro DE Der Fall ist eingetreten, mit dem viele von uns gerechnet haben. Wir werden ständig und allumfassend überwacht und es sieht nicht so aus, als könnten uns Crypto oder Politiker davor bewahren.

Diese Tatsache hat auch schwerwiegende Auswirkungen auf den Aktivismus gegen Überwachung. Wie können wir gegen Überwachung kämpfen, wenn eh alle wissen, dass sie überwacht werden? Werden sich die Menschen zum Beispiel trotz NSA noch gegen die Vorratsdatenspeicherung mobilisieren lassen?

Die Überwachungsdebatte tritt in eine neue Phase ein, in der es nicht mehr um das Bit "überwacht/nicht überwacht" gehen kann, sondern wo Überwachung differenziert betrachtet und qualitativ eingeordnet werden muss. Dazu will ich ein paar Vorschläge machen. Slides

Secure eMail Storage with qpsmtpd + GPG Byterazor EN Because of the current actions against secure eMail providers in the USA (for example Lavabit) eMail security gets more and more important in the world. The current implementations of MTAs, POP3 and IMAP Servers do not provide a secure eMail storage. Adding such a secure storage is not trivial, because the encryption keys have to be stored at the eMail provider, enabling organizations to get hold of this key and decrypt the eMail. To prevent this, an asymmetric encryption standard has to be used. The eMail provider encrypts incoming eMail with the recipients public key and the recipient, after downloading the eMail, decrypts it with his private key. This talk presents a plugin for the QPSMTPD SMTP server, which does exactly this. Every incoming email is encrypted with the recipients PGP public key in the PGP-Mime standard, if this key is locally available and trusted. After encryption the eMail is forwarded by SMTP to the backend Mailserver. This method can easily be adapted to any other queuing plugin for the QPSMTPD daemon. QPSMTPD GPG Plugin Slides
Online Footprint - An experiment in privacy Hiromipaw EN While social media are increasingly opening up new possibilities for users to share and interact with people and content online, it has also become apparent that, as networking systems evolve and online interactions become more frequent and complex, it is always more difficult to retain control over our online footprint.

This work is hence concerned with the modelling the user online footprint as a result of the aggregate activity collected across different services online, calculating the risk that a user can be subjected to a particular attack, hence profiling known attacks, and finally helping the user to maintain a desired online footprint by adopting certain privacy enhancing techniques.

Web 3.0 - reconquest of freedom on the Internet - a social movement? Klaus Wallenstein DE The protest against the total surveillance on the Internet fizzles been ineffective. Still, data are skimmed off by intelligence agencies and Internet companies masse.

Why it has not yet come to political progress? What should change in the future so that society and politics finally respond appropriately to the problem?

Einigkeit für Recht und Freiheit - Für eine gemeinsame Bewegung gegen Überwachung Ramses DE Seit Edward Snowden seine Enthüllungen begonnen hat, gibt es auch in Deutschland eine breite Front von Organisationen, Initiativen und Einzelpersonen, die sich gegen die zunehmende Überwachung wenden. Dieser breite Protest ist jedoch sehr zersplittert. Es gibt viele Einzelinitiativen, die zu großen Teilen nicht zusammenarbeiten. Vielmehr gibt es sogar erhebliche Differenzen zwischen den Gruppierungen, obwohl die Ziele oft nahezu deckungsgleich sind. Aktionen der anderen werden kritisiert, man streitet über unwesentliche Details. In diesem Lightning Talk Rant möchte ich aufzeigen, dass das anders werden muss und die verschiedenen Initiativen und Organisationen vereint auftreten müssen, wenn wir das erreichen wollen, worum es uns letztlich allen geht: Recht und Freiheit.

A successful full-scale implementation would open the technique to a wide range of security-critical code.
