a non-peer-reviewed, non-institutionally-affiliated, single-authored e-publication on the topic of government-sponsored cryptography, which mentions a conspiracy theory in its opening paragraph, might be making some incorrect assumptions and drawing unsupported conclusions?? you don't say

yeah i think they may all be fake names - no hits on google scholar for any of the three authors - no relevant hits on google proper either, for that matter - each name is super generically english, yet the paper reads like it's written by an EFL writer - the very first three words in the paper read "SIMON et SPECK" instead of "SIMON and SPECK", which is a bizarre error to make unless you translated it from french or the author is unconsciously code-switching - i can find no reference to the "alba3" group they say they're part of - but "alba3" is a pun in french: alba-trois, albatross i think it's a wacko conspiracy theorist and/or amateur mathematician whose first language is french who has added a bunch of academic embellishments to his zine to try and get his ideas more traction than stapling them to a telephone pole can provide

i've got a question about old cryptography that y'all can probably answer: so i know that in world war 2, the allies used that weird robotic voice SIGSALY system for their highest-level communications. what did the axis powers use for that same role? was it just some more complicated variant of a rotor-based system like the enigma machine?

I don’t think there was an exact equivalent, ie a cipher developed specifically for top level communications between different axis powers. they didn’t trust each other that much or work together as closely as the uk and usa did. for example, German communications with japan pretty much all went through the Japanese ambassador - hitler didn’t talk to hirohito directly or anything - and the ambassador just used standard Japanese codes, which were terrible and regularly broken by the allies. so the closest thing was probably the german Lorenz cipher, which hitler used personally to communicate with military commands. it was a rotor-based cipher but quite different from enigma - it was basically an early stream cipher operating on 5-bit characters. the british figured out how it worked just from a few instances of key reuse, then built colossus to break it.

IIRC the inherent dysfunctions of the axis meant that the KM in the med gave away a lot of italian navy plans and action because the german codes were broken but (at least at one point) the italian ones weren't, because the germans had to play Senior Partner all the time and so on

gonna be a huge dumb pedant and point out that the 'russians used a pencil' thing is a myth. the soviets used grease pencils because a graphite pencils crumble in low g and poo poo up electronics and air filters. the 'astronaut pen' was developed as a gimmick by a pen company and eventually adopted by both programs. ballpoint pens work fine in low g, they only don't work when you turn them upside down in normal gravity

(I believe the Germans and Russians did both develop voice encryption devices, or at least obfuscation? but they weren’t very secure or widely used.)

i think that's one of hte more infuriating parts of this article. It's not a security question, it's a text box where the recipient has to type a passphrase and the sender can either send them a hint (gently caress no what is wrong with your brain) or utter gibberish, because the arrival of $1800 probably isn't a surprise and you can mention the password when you tell the person the money is coming Q: fieopwje hiasfj pwefhj23fiodajf o2038foisljfjasdfdaspfjfjdfjjjjjjjjjjjjjj A: eighteen kilograms of poo poo in a thimble e: i tried ending the answer with a sql injection type phrase (single-quote or one equals one) and got a cloudflare block message lol flakeloaf fucked around with this message at 16:57 on May 13, 2019 |

haveblue posted:what are the odds that you don't type in the name of your favorite beatle but pick it from a dropdown It's not strictly a security question. When you do an interac e-transfer in Canada, you put in the recipient's email address and it sends them a "claim your money" link. There is no verification of the email address, so you have to also write a question where the answer is known only to you and the recipient. This question can be whatever you want, though, so there's nothing stopping you from making it "what is 2+2." I haven't done one in a while, but I'm pretty sure that once you get the email and answer the question correctly, that's the end of it and you can deposit the money into any account you want. Really it's just surprising that no one has reported on it until today Yes, obviously the correct response is to make both fields a bunch of hexadecimal junk but that isn't how people's brains work Sagebrush fucked around with this message at 17:02 on May 13, 2019 |

Really it's just surprising that no one has reported on it until today yup, that's exactly how it goes an email arrives saying "Hi, [whatever the sender calls you], Sendername sent you $420.69 (CAD). Click here to deposit to the bank we know you bank with, or click there to put it somewhere else" once you have that email you're a facebook "getting to know you with 50 questions" quiz away from fabulous riches if you've lost control of your email account, surprise surprise, someone else can read your emails and click things you sent, but yes, a clunker like that is exactly the sort of thing cbc marketplace "investigates" cutting-edge stories this year include: "Inuvialuit pay too much for southern food", "FTD are shite" and "Always-on security cameras and microphones in your house are watching and listening to you" flakeloaf fucked around with this message at 17:12 on May 13, 2019 |
