Here I wrote you about the real reason of difficulty to unlock iPhone passcode. Nobody can do this, even machine. And it is all about iSecurity. Simson L. Garfinkel, a specialist working in the field of computer forensics and digital criminalistics, claims that Apple with the iPhone has stepped over the threshold of complete safety. Even this year Apple specialists visited Black Hat Conference to ensure in its safety. iPhone passcode has a security architecture, originally built in its hardware and software, says the expert. And the owners of the devices can use encryption technology to their personal data, which will not be able to unlock even by the intelligence services. Currently, iPhone and iPad are reliable mobile computing systems, which can be used for mobile payments, e-commerce and software supply, thanks to large cash investment in Apple security. Even law enforcement can not perform forensic iPhone expertize, seized from criminals. You can't hack iPhone passcode because it uses the encryption algorithm - AES, which was adopted in 2002 as the standard of U.S. state services. National Institute of Standards and Technology of the United States published its specification after the five-year period during which they are created and evaluated 15 candidates. According to Garfinkel, in June 2003, the U.S. National Security Agency has decided that the AES cipher is reliable enough to be used to protect information classified as classified information from hacking. Up to the level of SECRET were allowed to use a key length of 128 bits, for TOP SECRET level required key length of 192 and 256 bits. As one of the researchers of the standard said: "We need a trillion machines, each of which can test a billion keys per second. Still, there will be need for more than two billion years to restore the key AES-128. " Now you see that it is almost impossible to bypass or unlock iPhone passcode so don't even try it, however, who knows, may be you will be the one.
