I remember reading that Arthur C Clarke story where one side loses the war they were previously winning because they keep putting untested weapons into full production, and I always thought nobody was that stupid.

Oops.

That story is cool. I forget what it was called though, but it was told from the point of view of a surrendered high-ranking officer from the side that was winning until they started putting in more untested half-assed improvements.

crucial really dropped the ball there, surprised at how well the evos held up given they're by far the more popular brand. comparison with regular and pro would be interesting, and more recent versions/brands in-use

only real issue i have is that these aren't exactly sold as secure solutions and this relies on bitlocker ignorance by the people using it (so a 1:1 overlap on a venn diagram)

e: worth reading the replies by one of the authors of the paper https://twitter.com/bvgastel/with_replies

i was expecting the crucial variety of issues to be more widespread, but they didn't exactly have a lot of devices to mess with

if more detailed research happens in the future i'd be surprised if crucial were the exception

so what the gently caress was MS thinking letting the drives handle the key management instead of leaving that to the TPM and just releasing the key to the drive at boot so it could accelerate the AES instructions. You can still gently caress that up too, but the scope is much smaller and easier to validate.

it sounds like that's what they're doing, the problem is the drive accepts any key to decrypt

No, it accepts any password, not any key. That's not how AES works.

The key _should_ be derived from the password but apparently it's simply stored somewhere on the SSD unencrypted and the drive only does a very simple password check.

my read was that once bitlocker saw the drive supporting hardware encryption they just turned it over to that entirely

quote:

OLD PARADIGM ( 1998-2015 )
Memory is expensive and computing devices did not have constrained resources​
Use memory sparingly
Use wired computing power
Calculate matrix algebra to encrypt/decrypt data​
Classic encryption​ is CPU intensive to encode (14 processes),
decode (14 processes) and utilizes 100 algorithms requiring 3MB of storage

NEW PARADIGM ( 2015 - PRESENT )
Memory is cheap and IoT endpoints have constrained resources
Use more memory for algorithmic instruction implemented in C-code
(trades use of CPU cycles for use of RAM)​
Obfuscation beyond classic encryption​
CPU light to encode (1 process), decode (1 process) and utilizes 2 algorithms
with only 2.4KB​
Battery powered – limited / finite energy source​
Use linear computation of key space
Relies on algorithmic instructions implemented in C-code as opposed to
mathematical equations
Fast, energy efficient and agile​
Facilitates one-way-functions​

wow, C code instead of mathematical equations!

ssds are gimmick devices that prosumers gobble up in droves because they've been told that they're faster without actual direct knowledge of their performance vs. a good quality hdd

when actually used for functions more intensive than just browsing facebook and checking email in a $2000 custom rig, surprise surprise they're terrible and unreliable

the tip-off should be that they're all peddled by fly-by-night garbage vendors like ocz and crucial

this is a poor analogy because with vinyl, the difference in quality is largely a matter of taste and nostalgia vs. other forms of media that offer more convenience or modern advancements in sound fidelity

it's not that hdds : vinyl :: ssds : mp3s, it's more like hdds : vinyl :: ssds : listening to a dog's rear end while it shits right into your ear

God help me, I know im reply to Stymie, but can't you conceive of workloads where random access performance is more important than sequential access? Like no matter how fast HDDs get they can't compete on that metric vs ssds.
