Always wanted to learn how a "key exchange" works? Wonder what is the difference between symmetric versus asymmetric encryption? Not a maths expert but curious about how cryptography works? Reading this and wondering what any of this means?? Fear not, for you are in the right place! This will be an interactive workshop where we will briefly go through various key (no pun intended) cryptography-related concepts, including (but not limited to!) the Diffie-Hellman key exchange, One-Time Pad, hashing, and transposition ciphers, using visual art including painting and paper. The concepts will be at an introductory, high level (no maths, etc.). So come learn about cryptography basics in a fun way, and take home your very own abstract art, while you're at it! There will be some space themes. This session is mainly geared for younger audiences such as children (e.g., 8-18 years old), but any age is welcome, including grown-ups.
