A small town library in New Hampshire joins the anonymous Web surfing service Tor. Then the Department of Homeland Security shows up.

Hidden messages? Check. Cheating? Check. Seems on-topic for this course!

And here's that visualization of Girl Talk's 2010 album, All Day, that I showed in class.

Here's a 2008 New York Times piece on Girl Talk. Whether or not his fair use argument would hold up in court, it seems clear that music labels aren't particularly interested in suing him for his all-sample approach to music creation.

And here's Bruce Schneier on that story about Apple's encryption policies thwarting justice. If you read the first piece, you should also read this one.

Here's a recent piece by security expert Bruce Schneier on quantum computing, which is different than quantum cryptography. (I conflated the two during class today.) Quantum computing is very fast computing that could be used to quickly break modern encryption schemes. Quantum cryptography involves sending messages that can't be read, since "looking" at them changes the message. Schneier offers some conjectures about where the NSA is with regard to both technologies.

This 99% Invisible podcast episode focuses on locks and lockpicking. I think you'll find some nice parallels with cryptography, especially around Kerckhoff's Principle and the idea of not knowing if your security system has been broken.

"Over time, all data approaches deleted, or public."

I was just followed on Twitter by someone from Blockstream, which looks like a start-up based on crypto currencies like Bitcoin. Fascinating.

"A few months ago, an officer for the Byron Police Department in Georgia made a routine traffic stop equipped with an unusual piece of technology: Google Glass."

We'll give Mailvelope (the webmail encryption tool) a try in class tomorrow. See Step Three for instructions.
