Question PAD LOCK & Security

Hello all,
Just received my new usb key, a pad lock 2go, I just wanted to ask some questions.

- is there any way for someone who could find it to reset my pin code and access private data ?
- Could it be reseted by opening the key and removing the battery ?
- is there any kind of protection between the pad and the usb key itself ? I mean, i did not open the usb key, but I assume there is a kind of encryption between the pad and the stick itself as it sounds like to be glued over a standard flash disk reason of his size.

thanks!

A: No once the code is set there is no way to reset the drive, if you loose or forget the pass word you would not be able to access the drive.

- Could it be reseted by opening the key and removing the battery ?

A: NO the password is in the firmware and there is no way to reset it with out knowing the pass word you set. The battery just powers the keypad and LED's

- is there any kind of protection between the pad and the usb key itself ? I mean, i did not open the usb key, but I assume there is a kind of encryption between the pad and the stick itself as it sounds like to be glued over a standard flash disk reason of his size.

A: No but we will in a later version encrypt the data on the fly so it is more secure. IE in other words if someone takes the memory chips and installs them on another unit that is exactly the same they might be able to read the data on the drive. However. 90% of the time the unit would be destroyed to do this type of swap as the housing is bonded to the PCB.

So what happens if you forget your password, assuming you didn't register it?

I was reading the Flash Padlock page (http://www.corsair.com/products/padlock.aspx) and the PDFs attached to it, and I had some further questions.

Flash Padlock User Manual
Flash Padlock App Note
Flash Padlock Whitepaper


I see that the PIN can be anywhere from 1 to 10 digits in length. When you are entering in the combo, you really only have 5 possible buttons to use. WARNING: CALCULUS (IIRC) AHEAD!

So instead of there being (the summation of n=1 to 10, where the equation equals 10 to the power of n) 11,111,111,110 possible combinations, there's really only (the summation of n=1 to 10, where the equation equals 5 to the power of n) 12,207,030 possible combinations, correct?

[that's all possible combinations added together for PINs 1 to 10 digits long. Comparing PINs that are only 10 digits long, that's
10,000,000,000 versus 9,765,625]

The manual has instructions to set the device to "always unlocked" mode. After this mode is set (which the manual does state can only be done from an unlocked mode), and you re-lock it, the PIN can be different from the initial PIN, correct?


The following questions may or may not be best answered by ClevX, your call RG and JF :)

Note: Unless I missed it, on the Whitepaper, 5 APPENDIX: AUTHENTICATION COMPARISON TABLE, at the end it says:
** User must remember backup password

However, ** is not used in the table at all.


Now, the white paper mentions that ...
Quote:
An auto-locking feature allow Padlocks to lock themselves when removed or the host shuts down. If the drive is unlocked under battery power, it will automatically re-lock if a host is not detected within 15 seconds.
Could someone disconnect the device from one PC, and connect it to another, and still have full access to the device's information?

What is the battery life of said battery within the device?

What happens if / when the battery in the device dies?

A: Honestly I have not personally sat down and done the math but that sounds about right I am not sure if there are any other limitations that I am not aware of but I will check and let you know if this is not correct.

A: The user has to remember the password there is no way to recover it.
and If I understand you correctly it has to be a number.

A: No it will lock automatically and you would need to enter the code to use it on the new system.


Quote:

A: The Pad Lock has a Two Year Warranty if the battery dies and its under warranty we will replace it. And I am sorry the batterY is not user replaceable.

I was reporting a typo, there's no question there :)

The wording in the manual seems to refer to being able to change it when in this "always unlocked" mode, but maybe tat's just me

What about the 15 second delay the manual mentioned?

A: Da! Sorry, I just walked right by that LOL Sorry! It refers to the ** at the bottom of the page if I understand it correctly.

A: When its in Unlock mode you can change it but it has to be unlocked first then U can change it. Other wise it will not accept the password.

What about the 15 second delay the manual mentioned?
A: The delay is hen the password is set, or in other words once you enter the pass word you have 15 seconds to confirm it other wise it will not be set, and you have 15 seconds to enter the pass word or it will not unlock. The delay starts when you enable or start the lock/un-lock process.

But to be sure I will get one of the drives in the next few days and make sure for you.

Well ... I though it was a 10 year warranty ? So what's next after this two years ? Should I send you back my padlock device to change the battery ?

Thanks for all these answer !

The warranty page sayss USB sticks have a 10 year warranty, although the Pad Lock model is not listed.

http://www.corsairmemory.com/warranty/default.aspx

Please clarify the warranty / update the warranty page if it is in fact 2 years, thanks!

The merchant told me that it was covered by a 10 year warranty ... Strange that you mention only two years here .. ???

About your previous reply concerning the encryption on the fly.

"... but we will in a later version encrypt the data on the fly so it is more secure ..."

Could it be part of a firmware update ... Or will it be a totally new version of the PADLock ?

Thanks!

Sorry the Pad Lock is 2 year warranty!
And Yes, no and Yes!
It will be in a newer version maybe next year and will be more secure but older model will not be up-grade able.

Is that normal that if I disconnect my padlock from my laptop (xp sp2), and connect it to my imac, I get access to the data it contain without having to enter any access code ?

No if you remove it it will lock the drive and you may have to enter the pas word again.

Did this actually happen, or is this a theory? If the former, then try waiting 20 seconds, and seeing if it still works, or if you need the PIN.

Wait!
I was not correct, the device will always give you a 15 second delay before it locks. So if you remove it and insert it with in 15 seconds it should stay unlocked. As long as the green light is blinking when you move the drive it will stay un-locked.
