16. Brute Force Protection

What is a Brute Force Attack?
A brute force attack is a method of defeating a cryptographic scheme by systematically trying a large number of possibilities;
for example, a large number of the possible keys in a key space in order to decrypt a message.
In most schemes, the theoretical possibility of a brute force attack is recognized, but it is set up in such a way that it would
be computationally infeasible to carry out. Accordingly, one definition of "breaking" a cryptographic scheme is to find a
method faster than a brute force attack.
How does the diskG protect against brute force attack?
1. With the drive locked and in the standby state the LED indicator light will be
solid RED.
2. After five consecutive incorrect User or Admin PIN entries, the keypad will
not respond and LED indicator light will turn off. The drive will need to be
unplugged from the USB port and replugged. This will be repeated for each
five unsuccessful attempts.
3. Following the 10th incorrect PIN entry, the keypad will lock and the indicator light will begin
blinking rapidly. Even after unplugging and replugging in the unit, the drive will remain locked
and the LED indicator light will continue to blink rapidly.
4. Here are the steps to allow the user to unlock the keypad for 10 more attempts
to unlock the drive.
a. Unplug the device from the computer.
b. Push and hold the number five key and plug-in the drive.
c. The LED indicator light will be blinking, alternating
d. Enter the code 5278879 and press the
e. The keypad will unlock and will be in the standby state with the LED indicator light
solid RED, this will allow only 10 more attempts.
f. After a total of 20 attempts the drive will remain locked with the LED indicator
light flashing RED quickly. You must now go through the reset process and
reformat the drive to be able to use the drive again (see page 15 - Completely
resetting the diskG).
