Last week Apple released its new iOS 8 operating system for iPhones, iPads, and iPod Touch devices. Most of the coverage of iOS 8 focuses on visible features that users can interact with. But there’s one major change in iOS 8 that most users probably won’t notice unless they find themselves in a great deal of trouble. Specifically, Apple has radically improved the way that data on those devices is encrypted. Once users set a passcode, Apple will no longer be able to unlock your device—even if ordered to do so by a court. While privacy advocates have praised Apple’s move, it has drawn fire from some notable legal scholars. Writing in the Washington Post on Sept. 19, Orin Kerr referred to Apple’s new policy as a “dangerous game,” one that “doesn’t stop hackers, trespassers, or rogue agents” but “only stops lawful investigations with lawful warrants.” While Kerr has moderated his views since his initial post, his overarching concern remains the same: By placing customer interests before that of law enforcement, Apple is working against the public interest. If you interpret Apple’s motivations as Kerr does, then Apple’s recent move is pretty surprising. Not only has the company picked a pointless fight with the United States government, it’s potentially putting the public at risk. The only problem is that Kerr is wrong about this. Apple is not designing systems to prevent law enforcement from executing legitimate warrants. It’s building systems that prevent everyone who might want your data—including hackers, malicious insiders, and even hostile foreign governments—from accessing your phone. This is absolutely in the public interest. Moreover, in the process of doing so, Apple is setting a precedent that users, and not companies, should hold the keys to their own devices. To see why this is the case, you need to know a bit about what Apple is doing with its new technology. The first time you power up a new iPhone or iPad, you’ll be asked to set a passcode for unlocking your phone. This can be a full password or just a 4-digit PIN (though the former is certainly stronger). On devices with a Touch ID sensor, you’ll also be allowed to use your fingerprint as a more convenient alternative. A passcode may look like flimsy security, but it’s not. The minute you set one, Apple’s operating system immediately begins encrypting your phone’s sensitive data—including mail, texts, photos, and call records—using a form of encryption that the U.S. government uses to protect classified military secrets. The key for this encryption is mathematically derived by combining your passcode with a unique set of secret numbers that are baked into your phone. If all goes well, you’ll never notice this is happening. But the impact on data raiders is enormous. Even if someone cracks your phone open and attempts to read data directly off of the memory chips, all she’ll see is useless, scrambled junk. Guessing your passcode won’t help her—unless she can also recover the secret numbers that are stored within your phone’s processor. And Apple’s latest generation of phones makes that very difficult. Of course, your would-be data thief could try to get in by exhaustively trying all possible combinations, but according to an iOS security document, Apple also includes protections to slow this attack down. (In the same document, Apple estimates that a 6-digit alphanumeric password could take upward of five years to guess.) The encryption on Apple devices is not entirely new with iOS 8. What is new is the amount of data your phone will now encrypt. Apple has extended encryption protections to nearly all the data you produce on a daily basis and will also require you to enter the passcode (or fingerprint) each time you reboot your phone. In addition, if you purchase a recent iPhone (5S, 6, or 6 Plus), Apple will store your keys within a dedicated hardware encryption “co-processor” called the Secure Enclave. Taking Apple’s recent privacy announcements at face value, even Apple itself can’t break into the Secure Enclave in your phone. While it may seem “natural” that the designer of a system—in this case Apple—can break its own encryption, the truth is that such a capability is hardly an inevitable design outcome. For Apple to maintain such a capability with its newer security processors, it can’t just be more knowledgeable than its customers. It would have to literally design in a form of “skeleton key.” In computer security circles this mechanism is generally known as a “backdoor.” -- | ig/twit:@h4nafi | japri: ya[at]terserah.de | sent from tab°S° [4.4.2] | -- ========== Berubah menjadi lebih terkendali bersama @kartuHalo Halo Fit Hybrid Info Lengkap >> tsel.me/halohybrid #KendalikanHidup ------------------- Gunakan layanan Hosting Indonesia yang stabil, terjangkau dan aman Kunjungi >> http://www.Qwords.com -------------------- ID-Android on YouTube https://www.youtube.com/watch?v=0u81L8Qpy5A -------------------- Kontak Admin, Twitter @agushamonangan Aturan Umum ID-ANDROID >> http://goo.gl/NfzSGB Join Forum ID-ANDROID >> http://forum.android.or.id ========== --- Anda menerima pesan ini karena Anda berlangganan grup "[id-android] Indonesian Android Community " dari Google Grup.
