Aegis Padlock DT 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 denition of
“breaking” a cryptographic scheme is to nd a method faster than a brute force attack.
1. With the drive locked and in the standby state the LED will be solid RED.
2. After ve 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.
3. If the user, unsuccessfully tries to unlock the drive on the tenth 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 5 key and switch the Power button to ON on the back of the drive
3. The LED will be blinking alternating RED and GREEN rapidly
4. Enter the code “LastTry” (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.
