So they managed to invert a hash function and this somehow break AES?
Do they mean the key schedule? I don't remember AES using any hash function. Anyway, their solution is quantum key distribution.
How does key distribution solve the problem of the encryption algorithm being broken?
Or do they mean they didn't break AES at all, but the key distribution currently used for AES?

Comment Re:Unix time - leap seconds = happy days. (Score 1) 105

That already has to happen anyway. The only way a unix time stamp can be converted to current time is by checking a database to see how many seconds to add. Not just adding 37 seconds. Depending on the year you have to add a different amount. Anyway, this can all be handled by libraries. I really don't see the big advantage of being able to subtract to unix time stamps and not get the correct answer (the current situation) vs getting the correct answer. You need library functions to do the conversion from unix time to current time anyway.

Comment Re:WiFi is wireless, but... (Score 5, Informative) 105

Maybe actually read the paper and you will find out he is quite correct:

> As shown in Section V, the electromagnetic emissions generated by the data bus are around the 2.4 GHz frequency range and overlap the Wi-Fi channels. In Wi-Fi transceiver chips, the baseband processor handles the radio, PHY and MAC layers.The Internet, transport, and application layers are processed by the software protocol stack, usually in the kernel drivers. In order to measure the interference generated, the attacker has to access the low-level radio measurement information from the PHY layer. This can be done by compromising the firmware of the Wi-Fi chips and passing the required radio measurements to the software stack

So no WiFi signals were generated. They are using the PHY to measure interference in the WiFi spectrum, and this interference is then decoded. Using your definition a microwave emits WiFi signals.

Comment Re:What does this sentence mean? (Score 1) 318

Yeah, English is not my first language.
Also I googled "adjectival status of nouns" and only found references to Japanese.
I found some examples for English, but only where using an adjective as a noun, which wasn't the case in the sentence in question as far as I can tell.
Also, I speak what I consider to be television English. I do speak a pidgin as second language. Not sure it rises to the level of creole.
