My students @maxzks and Tushar Jois spent most of the summer going through every piece of public documentation, forensics report, and legal document we could find to figure out how police were “breaking phone encryption”. 1/
This was prompted by a claim from someone knowledgeable, who claimed that forensics companies no longer had the ability to break the Apple Secure Enclave Processor, which would make it very hard to crack the password of a locked, recent iPhone. 2/
We wrote an enormous report about what we found, which we’ll release after the holidays. The TL;DR is kind of depressing:
Authorities don’t need to break phone encryption in most cases, because modern phone encryption sort of sucks. 3/
I’ll focus on Apple here but Android is very similar. The top-level is that, to break encryption on an Apple phone you need to get the encryption keys. Since these are derived from the user’s passcode, you either need to guess that — or you need the user to have entered it. 4/
Guessing the password is hard on recent iPhones because there’s (at most) a 10-guess limit enforced by the Secure Enclave Processor (SEP). There’s good evidence that at one point in 2018 a company called GrayKey had a SEP exploit that did this for the X. See photo. 5/

I just finished Eric Adler's The Battle of the Classics, and wanted to say something about Joel Christiansen's review linked below. I am not sure what motivates the review (I speculate a bit below), but it gives a very misleading impression of the book. 1/x
The meat of the criticism is that the history Adler gives is insufficiently critical. Adler describes a few figures who had a great influence on how the modern US university was formed. It's certainly critical: it focuses on the social Darwinism of these figures. 2/x
Other insinuations and suggestions in the review seem wildly off the mark, distorted, or inappropriate-- for example, that the book is clickbaity (it is scholarly) or conservative (hardly) or connected to the events at the Capitol (give me a break). 3/x
The core question: in what sense is classics inherently racist? Classics is old. On Adler's account, it begins in ancient Rome and is revived in the Renaissance. Slavery (Christiansen's primary concern) is also very old. Let's say classics is an education for slaveowners. 4/x
It's worth remembering that literacy itself is elite throughout most of this history. Literacy is, then, also the education of slaveowners. We can honor oral and musical traditions without denying that literacy is, generally, good. 5/x
As someone\u2019s who\u2019s read the book, this review strikes me as tremendously unfair. It mostly faults Adler for not writing the book the reviewer wishes he had! https://t.co/pqpt5Ziivj
