You're probably familiar with the phrase "pleading the Fifth." You know, that thing the defendants on crime shows do when they're obviously guilty and they just don't want to talk about it. Well that's also a thing in real life, and it isn't a de facto admission of guilt. For the unfamiliar and forgetful, the Fifth Amendment states that no person, "shall be compelled in any criminal case to be a witness against himself," as well as a bunch of language about like, eminent domain and stuff. The point here being that the 11th Circuit Court of Appeals has just ruled that a defendant in a legal case who refuses to decrypt their hard drive for law enforcement is covered by the Fifth Amendment.
Most of us probably don't give much thought to the digital encryption systems that keep our personal information, well, personal. If you do, you probably know more about it than I do. That said, the news that encryption keys can be stolen from smartphones by would-be nefarious hackers using only a nearby AM radio sets off all sorts of alarm bells in my head. Fortunately, no one has fallen victim to this technique, and the exploit's discoverers at Cryptography Research hope to keep it that way.
