Cryptography spreads across our society like SARS-CoV-2, and will stick around like the seasonal flu. How to live with it and avoid broken-off handshakes and acute system malfunction syndrome? This presentation looks at using cryptography in the context of critical infrastructure, contrasting the stereotypical viewpoint of crypto as it appears in World Wide Web transport layer security. This is a second wave of a series on improving security through clarified structure*. 

The presentation targets people interested in cryptography for different demanding application areas, and aims to soften the bumps that lurk on the second half of the proverbial hype curve - may they all be flattened.
