    How do you prove that the evidence was not altered if the original is destructed?

    Testing a DNA sample is also destructive, as are many other forensic tests. The key is that you have a disinterested technician performing the analysis, documenting each step in the process, and later testifying about it. If necessary, you can also keep recordings of the whole process, and subject those to chain-of-custody rules. If you really, really want to be careful, you allow the defense to provide their own expert witness who observes the entire process.

    In addition, the process I described specifically does not destroy the original. The flash chips with the original encrypted data are intact, and so is the shaved CPU with visible microfuses. A defense expert can actually reconstruct the extraction and decryption process. There's still the possibility that the bits you read out of the CPU actually weren't the key but some other random thing, which is where those information-theoretic arguments I mentioned come in.

    This is actually pretty easy to make ironclad, completely challenge-proof, and the fundamental ideas are no different from those used in any forensic analysis.

    if the answer is not in the book, or computer or neighbor... then your teacher is just a sadistic asshole.

    Heh. My favorite math prof used to give "open anything inanimate", take-home exams. Each consisted of exactly eight problems, all of the form "Prove or disprove <statement>", and they were handed out on Monday of finals week, and due on Friday (some people asked for more time, but he said he didn't want to ruin our weekends). They were awesome, requiring deep understanding of the material but all of them were actually within the grasp of a good student. I never found any of them in any book; he created them all himself, I think. Most students only managed about 50%, but a few from each class managed 100% -- with 10+ hours of work.

    I don't think he was a sadist at all and definitely not an asshole. Those exams not only really showed who did and didn't understand the material, but they did an extraordinary job of cementing and combining the course's key elements in the minds of the students. Not as a replacement for homework, mind. If you hadn't been doing your homework there was no way you'd pass the exam unless you were a Ramanujan or something.

    I thought they were also great fun. I remember endless hours of staring at the ceiling while rotating the pieces around in my head, until finally they clicked and I saw how to prove the statement or construct a counterexample. My wife (just recently married) was startled the first few times I shouted "YES!" and started jumping up and down after hours of staring and aimless pacing, interspersed with occasional scribbling. She got used to it, though. Thinking back makes me want to go take some more classes from him (we remain friends today, some 25 years later).

    Another viewpoint: I really like Google+. It's by far my favorite "social" network. I put social in quotes because I think the key thing to understand about Google+ is that it isn't a social network so much as it's an interest network. It is for me now what USENET was 20 years ago, the place I go to talk to like-minded people about the things I'm interested in. It's better than USENET, though, because most of the newsgroups didn't have the moderation features needed to keep the signal to noise ratio high. I find I have a lot of really great conversations on G+.

    I saw a post (on Google+, actually) that captured it pretty well: Twitter is for following celebrities. Facebook is for following your family and friends. Google+ is for following your interests. I also use it a little as a social network, but mostly I'm in a bunch of communities and follow a bunch of people who do and talk about things I find interesting. Relatively few of them are people I've ever met in real life. However, there are a handful of people I met through G+ who have become really good friends. We've met in real life, and even hung out with each others' families and stayed in each others' homes when traveling. That's a strong indicator of the depth of conversations that I have on G+.

    Full disclosure: I'm a Google engineer, so I have a bias in favor of Google products. I also have a deep dislike of Facebook which probably isn't entirely rational any more. I say "any more" because that dislike is based largely on things Facebook did in the past and which I don't think they'll do again. I will probably give Facebook another shot, because it's the way my extended family stays in touch (lots of them are also on G+, but I think that's mainly because I am).

    the whole point of the FBI query is so they can maintain a legal chain of evidence in extracting the data. Everyone KNOWS the NSA can crack this by disassembling the hardware, but that method is not admissible in court.

    Cite?

    I see absolutely no reason that disassembling the hardware breaks the chain of evidence. Said disassembly just has to be done by experts who will testify to the steps they used to extract the data and that the device was not out of their control. The NSA might not want to testify to the means used, I suppose, but I don't see why not because this is a really straightforward process. It requires specialized skills and tools, but nothing not present in many university research labs.

    1. Remove the flash chips and connect them to a controller to copy the contents (which are encrypted).
    2. Remove the CPU, and shave off the cladding to expose the silicon wafer inside.
    3. Shave layers of silicon off to expose the non-volatile storage containing the key (likely micro fuses, which are relatively large compared to other features).
    4. Use an electron microscope to read out the key bits.
    5. Combine all possible passwords with the key bits in the manner done by Apple's software to produce all possible candidate encryption keys.
    6. Perform trial decryptions of the data obtained in step 1 with all of the keys to see which one works. Or Apple may have another mechanism to determine if the key is correct[1].

    There's nothing here that requires secret knowledge, and nothing that would somehow break the chain of custody. Before you can do this on the target phone you need to do it on a few others so you can identify the location of the key in the silicon. After you're done, you may also need to make some information theoretic arguments about the possibility that you screwed up and found something that wasn't the key but still produced plaintext that looked like actual data. Those are very easy.

    So, no, this isn't about chain of evidence. For that matter, it's unlikely that any data on the device would ever be used to prosecute anyone anyway. The (purported) goal here is to get leads that may identify other conspirators, and if that were to happen it would almost certainly be other evidence, found as a result of following those leads, that would be used to prosecute the other conspirators. The "fruit of the poisoned tree" issue that comes up with illegally obtained information wouldn't apply, because the leads wouldn't be illegally obtained. There are no legal obstacles to the FBI extracting whatever they can get out of this phone.

    [1] A common technique to determine whether the password-derived key is the correct one is to store a secure hash of the derived key alongside the encrypted data. This makes it easy to check whether the derived key is the correct one, but unless the hash is broken to the point of being reversible doesn't provide an attacker with significant information about the key, especially if the hash space is significantly smaller than the keyspace (e.g. 32-bit hash of a 256-bit key). Android device encryption uses this technique to check if your entered password was correct.

  22. Re:What a crock on Godfather Of Encryption Explains Why Apple Should Help The FBI (bgr.com) · · Score: 4, Insightful

    To wit the answer must be: "We re-architected our security hardware and no longer possess the *capability* to circumvent query limit and delay."

    They probably already did this in the 5S and later. The 5C does not have the "secure enclave" chip, which means there is no secure hardware on the device, all of the security is implemented in software.

    Also, it should be pointed out that the signed software approach is quite secure against anyone who doesn't have the software signing keys, or the capability to compel the holder of the signing keys. That's actually just fine if the goal is to defend the data from access by private snoops (e.g. spouses, even technically sophisticated ones, corporate espionage, etc.) and criminals.

    Consumer devices will never be secure against state actors with unlimited funds and sufficient motivation (e.g. NSA, GCHQ, Mossad, etc.), so really the only cases where the approach is inadequate are cases where (a) the owner of the signing keys (Apple) wants the data or (b) a government with the power to compel the owner of the signing keys wants the data. Apple has no reason to prevent their own ability to circumvent (though they do need to protect against use of this ability by rogue employees), since they know their financial interest is strongly on the side of securing the data, and legitimate companies generally do not expend effort on securing data against law enforcement officials of democratic regimes that have due process and rule of law.

    Indeed, although the 5S and the 6-series probably do make it impossible for Apple to comply with similar demands for those devices, I really doubt that was the rationale for adding the security chip. I'm the lead engineer for similar components on Android, and while I've been pushing to include a secure element chip for some time, the rationale has never been to keep US courts from being able to compel access, it's always been about strengthening security against corporate espionage (which signed software solutions do address, but not completely) and to make penetration costlier for oppressive governments and intelligence services. I say "costlier" since they can't really be kept out completely.

    I'm not certain that the secure enclave actually keeps Apple from being able to comply with this sort of request, either. I expect that the software in that device is also field-upgradable, since there are compelling practical and security reasons for enabling upgrades. Bugs are always a risk, and being able to fix them is a really good thing. But if the software can be upgraded, then it can be "upgraded" to remove security features. This can be limited in various ways; it's common, for example, to have secret keys burned into hardware which simply cannot be extracted by software because the software never has direct access to them, and any security that derives from the secrecy of such keys can't be subverted by software changes. But brute force mitigation possibly can be upgraded away, even with the secure enclave chip.

    The bottom line here is that these are really hard engineering problems. Not that it's hard to design so that key components are non-updatable... that's easy. But it's also very risky, because it leaves you without any options when said components turn out to have problems. I think it's flat wrong to characterize Apple engineers' failure to secure the 5C against Apple as any kind of incompetence, which is your clear implication.
