Rich Mogull on the Security Features of the iPhone 3GS

Rich Mogull:

The iPhone 3GS includes a hardware encryption chip that uses the industry-standard AES 256 protocol (that’s the Advanced Encryption Standard, with a key length of 256 bits). Hardware encryption enables a device - a phone, a hard drive, or what have you - to be nearly instantly wiped by erasing the encryption key stored on the device.
