Aegis Padlock Pro Brute Force Protection
What is Brute Force Attack?
In cryptanalysis, 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.
1. With the drive locked and in the standby state the LED is red solid
2. After six tries to enter the correct user or admin password the keypad will
not respond and LED will turn off. The drive will need to be unplugged from
the USB port and repluged. This will be repeated for each six unsuccessful
attempts.
3. If the user, unsuccessfully tries to unlock the drive on his 25th try the
keypad will lock and the LED will begin blinking quickly. Even if unplugging
and replugging the drive will remain locked with the LED blinking quickly
4. Here are the steps to allow the user to unlock the keypad for 25 more
attempts to unlock his drive.
a. Unplug the device from the computer
b. Push and hold the number five key and plug-in the drive
c. The LED will be blinking alternating red and green fast
d. Enter the code 5278879 and press button.
e. The keypad will unlock and will be in the standby state with the LED
solid red, this will allow only 25 more attempts
g. After a total of 50 Attempts the drive will remain locked with the LED
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 8)
