I'm glad to see some discussion regarding green cryptography. This is a concept of mine that started to take shape back in 2006, based on the fundamentals of mature and minimalist design. With recycling at its core, "green cryptography" seemed like an appropriate in-the-now moniker.
When my research took an AES-centric approach, I had the exceptional honor of being joined by Vincent Rijmen, whose wealth of knowledge and generosity helped shape our work into an extremely fun project -- one that we believe in and hope to see take off. We'll certainly be nourishing it along the way.
I must say, though: I am a bit jealous that I wasn't there to hear its introduction! Oh well -- that's why we have good recaps like yours. :)
