If President Obama was thinking of switching from BlackBerry to iPhone, he would be pleased to know that, thanks to its use of extremely strong encryption, the National Security Agency sees it fit to store top-secret data. After all, its own investigators failed to crack it.
According to Technology Review, the iPhone's use of Advanced Encryption Standard (AES) a data-scrambling system first used in 1998, makes it nearly impossible to crack. Even if you had one of the world's most powerful super-computers, you still wouldn't even be able to crack it.
At the heart of Apple's security architecture is the Advanced Encryption Standard algorithm (AES), a data-scrambling system published in 1998 and adopted as a U.S. government standard in 2001. After more than a decade of exhaustive analysis, AES is widely regarded as unbreakable. The algorithm is so strong that no computer imaginable for the foreseeable future-even a quantum computer-would be able to crack a truly random 256-bit AES key. The National Security Agency has approved AES-256 for storing top-secret data.
Also helpful is the fact that each iPhone's AES key is not recorded by Apple or any of its suppliers. And if someone does attempt to crack your iPhone, the key is erased and reset after 10 failed attempts.
