A Question of Entropy
We haven’t had a poll for a while so here’s one for your entertainment.
An article has appeared on the BBC Website entitled Web’s random numbers are too weak, warn researchers. The piece is about the techniques used to encrypt data on the internet. It’s a confusing piece, largely because of the use of the word “random” which is tricky to define; see a number of previous posts on this topic. I’ll steer clear of going over that issue again. However, there is a paragraph in the article that talks about entropy:
An unshuffled pack of cards has a low entropy, said Mr Potter, because there is little surprising or uncertain about the order the cards would be dealt. The more a pack was shuffled, he said, the more entropy it had because it got harder to be sure about which card would be turned over next.
I won’t prejudice your vote by saying what I think about this statement, but here’s a poll so I can try to see what you think.
Of course I also welcome comments via the box below…Follow @telescoper
