Slightly less "Quantum is an advertising term only used when you have nothing innovative" than usual! They're apparently using a QRNG (Quantum random number generator), instead of the usual CSRNG (Cryptographically Secure pseudoRandom Number Generator). This is hypothetically more secure, but in practice there's no difference and this is purely a marketing gimmick.

Yeah how many attacks have there been using the pseudo-randomness of the RNG to break into modern phones? Going to bet none.

The chip is a so-called Quantum Random Number Generator (QRNG). It uses quantum physics to generate truly random numbers to be used in the encryption

Neat, but not especially interesting. I'm not aware of any significant weaknesses in current PRNGs.

Just another worthless feature that's broken if you install a custom rom.

No one cares about custom ROMs for a Korea-only model that is clearly targeted at the business sector.

[-] potentiallynotfelix 2 points 2 months ago

I tend to buy business devices because they often contain less bloat or gimmicky features.

If a custom rom can’t support it, that’s more about the custom rom than Samsung here. They will almost certainly open source the kernel driver part, and any user library could be copied from the stock rom if absolutely necessary. If a rom developer doesn’t want to do that, well that can’t be reasonably pinned on Samsung.

I disagree, if this chip is anything like Knox protection, it will self-destruct if tripped, which is intentional to prevent the rom dev from making use of it.

What is the state of Samsung kernel building? Last time I tried, they met the letter but not the spirit of actually providing usable source code.
