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-defence, 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!
