I guess the sentiment is everyday individuals and not the corporates and the wealthy. Financial benefits of advancements rarely seem to benefit common folks
If I had been the project leader on this it would have had an even greater capacity because I would have taped a couple of keyring flash drives around the edge.
Anyone else convinced AES-256 is not long enough a but length for full disk encryption anymore? Even the 512-bit schemes are just trying some offset-salts that, with ~10TB I worry about providing close-enough statistical significance for cryptanalysis.
With 100TB drives?! I am less worried and more... convinced its a problem.
I have to admit, that I never looked into the technical details of full disk encryption
If I understand you correctly, they are using the same key for all the data and with larger amounts of data statistical analysis becomes feasible
Did I get this right?
Couldn't that be solved by using a root key + salt per block/sector/file/whatever?
I'd still only need the one root key and with every block the actual encryption key changes
I was thinking about perfect forward secrecy and that was the first thing, I could come up with
But, I'm absolutely not a crypto/math guy, so probably I don't know enough to really add something to the discussion/solution...
At the current rate of development, every city will have its own space heater data center, so with all that computational power available to just any maligned local city government dignitary, you're right to be concerned.
I assume this is not something I need to worry about with 1TB drives at all? That's a pretty cool fact about cryptography/data storage I did not know, thanks for sharing

Those Yankee sanctions really keep backfiring, don't they?

Wouldn't it be great if this would benefit us, real people?

They're needed just to hold the massive encryption key, I'm assuming.

Even if quantum cryptography were real, its been proven not to affect symmetric encryption like AES.
Don't use AES-GCM for your block cypher.

Youngster. Bet you've never even seen an 8" floppy IRL. And don't get me started on tape or punch cards...

I saw Punchcards in my military service and in the payroll office in my job later.

Yeah, but it's only about 12tb after you format it. Probably.

With all the data retention and logging requirements being imposed by various governments, your "joke" might not be so far off.
