This article is the second post on security terms explained in easy, every-day-life examples. The first post can be found here.
We meet our friends Alice and Bob again, who send each other letters and Eve, who doesn’t like what they have. Eve therefore tries to have a look in their letters, trying to find out secrets about Alice and or Bob to gain advantage she can use against them.
Let’s imagine following scenario: Bob has bought a new lock to his mailbox. This lock is advertised as the ultimate smart lock, with machine learning, blockchain and AI and has a simple button that recognises the user. Unfortunately Bob ordered the lock on Wish.com (reference for readers from the future: back in 2021, this was an internet shopping platform for cheap stuff, with often surprisingly bad outcome). The lock arrives and exactly as the description states, consists of only one single black button instead of a keyhole. Bob installs the lock and is very happy. Each day, he simply presses the button and the mailbox opens.
