Any actual source for this? (Like a waybill, or customs documents. Not a press release.)

The page you linked literally says "programs are written in C/C++".

"Arduino" is a programming language now?

Broadcom and Qualcomm, I think you'll find. Both of which are incredibly closed.

Well, it could be the CIA. It could also be a bunch of terrible quality PHP running a financial service worth $450m.

A fixed point in the compression function is not a vulnerability. Not sure why the post was deleted though.

Thank god they didn't publish their factorisation. My 4-bit RSA keys are safe!

So, does this work with YouTube and all the other google properties?

This is an example of a wide-pipe hash function, not a sponge.

Doesn't? It's already a much bigger problem than Windows XP. There are billions of Android devices shipped each year, and a miniscule proportion get updates. Even the best devices for updates only get them for a couple of yea

Did beddit actually ever make a product that worked? Certainly the indiegogo version I got never worked in any useful way.

Quantum cryptography is not unbreakable. See, for example: https://arxiv.org/pdf/1106.3224.pdf (Insert usual quote about the difference between theory and practice.)

It's not too surprising that a high-level I2C abstraction looks less convoluted than a register-level I2C driver. Here's the equivalent code for the Atmel peripheral: https://github.com/arduino/Arduino/bl

Dubai is really not safe for unmarried couples. It's a total non-starter, even for a holiday.

The standards group in question is unfortunately impotent. Two totally reliable voting blocs: the browsers and the CAs. There are more CAs than browsers, so the result of every vote is in the favour of the CAs.

Do you really believe that this team has the skills and knowledge to find these bugs and construct working exploits for them, but then don't understand the exploit market? Or, that they act against their own best economic interests?

The obsession with C/C++ here is really weird. Like, take the MCO failure. That's a classic, textbook problem that can be structurally guaranteed not to happen with use of even a basic type system. It should be literally impossi

Danger: truncation shouldn't be done by just chopping off the end of a hash; they should be different hash functions with entirely different images. Compare, for instance, multihash's treatment of SHA512 truncated to 256-bits, a

> Does anyone know why hash algorithms keep using such small state sizes, leaving us vulnerable to this same issue? Because small internal state is not actually the issue. SHA-1 was broken with 2^63 work, not 2^80 work. That discrepanc

No mention of SGX; a major Skylake feature for cloud computing. Is it enabled? Is it accessible?

It's PBKDF2 with SHA1, 4096 iterations and 32 bytes of output. That's relatively weak, and thanks to the defective structure of PBKDF2, an attacker will parallelise each output block.

This is not even remotely close to being true. Shor's algorithm runs in polynomial time.

Go has data races, which can break memory safety in some limited cases: https://research.swtch.com/gorace

I don't really understand why this doesn't cover memory safety.
