Aegis Padlock Brute Force Protection
What is 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 denition of “breaking” a cryptographic scheme is to nd a method faster
than a brute force attack.
Brute Force Feature
After FIVE tries entering the incorrect user or admin PIN attempts, the keypad will not
respond and LED will turn off. The drive will need to be unplugged from the USB port and
re-plugged.
If the user, unsuccessfully tries to UNLOCK the drive on the 10th try the keypad will lock
and the LED will begin blinking RED quickly. Even after unplugging and re-plugging in the
unit, the drive will remain locked and the LED will continue to blink rapidly.
Here are the steps to allow the user to unlock the keypad for 10 more attempts to
unlock this drive.
1. Unplug the device from the computer
2. Push and hold the number ve key and plug-in the drive
3. The LED will be blinking alternating RED and GREEN rapidly
4. Enter the PIN 5278879 and press UNLOCK.
5. The keypad will unlock and will be in the standby state with the LED solid RED, this will
allow only 10 more attempts
6. After a total of 20 Attempts the drive will remain locked with the LED ashing RED
quickly. You must now go through the reset process and reformat the drive to be able
to use the drive again.
