The other day, I learned about the Up-Goer Five Editor - a text editor that challenges you to explain something using only the 1000 most-used English words.
Attribute-Based Encryption (ABE) is a way to lock something away using “key”-words. Only people who have the keywords in their key can open the lock. The name of the approach comes from; ‘Attributes’, which are really keywords like those you enter into the search box; and, ‘Encryption’, which hides the thing.
