Jot: Digital Cinema Encryption

Article on the encryption of digital movies with the Advanced Encryption Standard, for example the latest Star Wars release, which
"is shipped to a theater on a hard drive, according to Technicolor Digital Cinema President Ahmad Ouri. Once it's been confirmed that the theater has received the encrypted film and loaded it onto a server, the encryption key is then delivered separately. "The film is useless without the key, and the key just tells the projector it's OK to show the film." In other words, it does not allow the movie to be copied in any way off the server."
