Are there encryption technologies that don't have a backdoor in them?

Sadly recently BitLocker has been cracked in 43 seconds. I do use BitLocker on all my systems, it's part of the image and scripted in PowerShell. But I don't feel safe that any 3rd entity like police or some other knowledgeable tech guy or whoever can crack any of my BL-encrypted drives

From my perspective, only I am supposed to be able to access my data. This is one of my primary issues with public cloud like G-Drive or OneDrive, it's gonna be someone else's computer in a Data Center., Like, I never store tax returns or any bills on my G-Drive or OneDrive accounts for this reason

Bitlocker and most other encryption protocols don't have backdoors. The attack you're talking about happened due to bad board design.

It also required a specific set of skills most people don't possess and also required a TPM that was separate of the CPU. If the TPM is integrated into the CPU this attack doesn't work.

The flaw (not backdoor) is that the key is passed on the wire in plain text from the separated TPM and the guy was able to guess on the signal timing ( the timing signal wasn't exposed ) and then had to build a proto type board and custom code to capture and decode that signal into a plain text bitlocker key.


You could in theory not use the TPM for your key storage and instead use a USB drive, but that is obviously susceptible to other "attack" aka it could just be stolen

Years ago, I had a company-issued Dell laptop fail from motherboard issues. While waiting for a replacement PC, they loaned me another Dell and I swapped in my old drive. Since BitLocker was mandated by corporate policy, I had to resort to entering my BitLocker recovery key which was printed on a piece of paper every time I powered on.

So yes, if you memorized that long string of digits then your key is secured in only one place. As @neemobeer notes, most encryption attacks are rarely directed on the encryption algorithm but exploit flaws in key management (people or software).

The "43-second-hacker" told viewers to activate the Bitlocker PIN protector against that attack.
