Guest Talk - Torsten Mutze - Origami and the mathematics behind it
In this talk we explore the mathematical and algorithmic theory behind the Japanese art of paper folding, illustrated with some beautiful models.
Guest Talk - Feng Hao - Tackling real-world security problems
Cryptography is a useful tool that often allows people to solve intuitively impossible problems with real-world impact. In this talk, I will present three examples from our previous research work. In the first example, I will show a technique that allows a user to anonymously send a veto message with untraceable origin even when all communication is under the strict surveillance, say by a big brother. In the second example, I will show a protocol that allows two remote users to establish a “high”- entropy session key from a “low”-entropy shared secret (password). The high-entropy session key can then be used for secure communication. In the third example, I will show a voting system that allows every voter to tally votes by themselves without needing any trusted tallying authority, while preserving the voter’s privacy. In each of these examples, cryptography is a key enabling technology that transforms the impossible to the possible.
