A public lecture about the fascinating history of ciphers, and an ingenious in its simplicity idea behind modern cryptography. You will understand how credit cards, Skype and online shopping take advantage of this idea and keep your data and money safe.



This lecture is for everyone! No knowledge of math or computers is necessary!



Number theory, a field of math that was considered somewhat useless, suddenly became indispensable in the XX century. Today it is in the core of cryptography, the backbone of all communication on Earth. Without it, internet would not be possible, nor would we be able to safely send emails, pay online or have private conversations on the phone.



Entrance is free but a donation of €3 (or more!) to fund the event is suggested and would be most welcome. If you have no loose change or coins we gladly accept payment via Visa Electron or Mastercard etc.!
