    The workshop Cryptography for Postcards introduces the basic principles of cryptography and cryptoanalysis with collaboratively created handmade ciphers and postcards.

    Cryptography as a means of secure transmission of information is a technology applied since the earliest days of human information exchange and did not loose significance. On the contrary, the current revelations concerning comprehensive surveillance and the resulting discussions about privacy are increasing. Cryptography is one aspect of digital self-defense, of how one can protect oneself and counteract.

    The workshop begins with an introduction of the terminology: text and code, key and encryption, language as an interpretation of signs and strings. It continues with basic cryptographic techniques finally explaining more sophisticated approaches like asymmetric encryption and quantum cryptography.

    The accompanying practical part will explore simple cryptographic mechanisms that the participants use to “encrypt” and “break” postcard messages.

    Bring your own postcards!
