In his excellent technical explainer about the Iphone decryption order, the Electronic Frontier Foundation's Joseph Bonneau discusses the actual process of cryptographically signing a new release of a major piece of Internet infrastructure like IOS.
Bonneau writes, "While we don't know what internal security measures Apple takes with its signing key, we should hope they are very strict. Apple would not want to store it on Internet-connected computers, nor allow a small group of employees to abscond with it or to secretly use the key on their own. It is most likely stored in a secure hardware module in a physical vault (or possibly split across several vaults) and requires several high-level Apple personnel to unlock the key and sign a new code release."
He goes on to compare the process with the DNSSEC Root KSK signing ceremony process, "a complicated procedure involving dozens of people," and mentioned that there was video online. There is! I watched it! You should too! It's pretty rad, solemn, techie, and interesting.
Zero-knowledge proofs are one of the most important concepts in cryptography: they’re a way to “validate a computation on private data by allowing a prover to generate a cryptographic proof that asserts to the correctness of the computed output” — in other words, a way to prove that something is true without learning the details.
Retroworks’ $18 decoder rings don’t have much by way of cryptographic robustness (they compare disfavorably to the cipher-wheel wedding rings my wife and I wear!), but they’re not a bad way to introduce the littlies in your life to the idea of habitual secrecy. (via Red Ferret)
This week (and next due to the nature of different release dates for the direct market and the book market) marks the release of the first collection of SHADE THE CHANGING GIRL v.1: Earth Girl Made Easy, which compiles issues 1-6 (previously). It’s a heavy load to recreate a character that giants before you have written. Steve Ditko is a master of the strange. His mind a merry-go-round of experimentation.
The Fader Stealth Quadcopter from TRNDlabs packs incredible flight performance into a package small enough to land on your phone screen, and it’s available now in the Boing Boing Store.The Fader’s six-axis gyroscope module gives it perfect balance in the air. This makes the onboard 720p HD camera all the better for shooting amazing flight […]
Although fully autonomous vehicles aren’t yet allowed on public streets, they are poised to dominate the roads in the not-too-distant future. But before that happens, Apple, Google, Uber, and other companies now investing in self-driving tech are going to need talented developers that can account for the dizzying array of factors at play when a […]
The PiCar-V learning kit comes with everything you need to build a Python-powered robot, and it’s currently being offered in the Boing Boing Store.
