Canadian man: I solved WWII WAR HERO pigeon code!

Re: Resources

UK the leaders in cryptography until they began relying on Microsoft computer technology.

Re: Resources

A small project like this is very useful as a training exercise and making sure cryptographers maintain a range of skills and look at a range of solutions.

Making snide remarks is not a required skill there BTW.

Re: Resources

Uk leaders in cryptography who actually invented public-private key encryption but due to the usual utterly short sighted british civil service mentality , decided not to reveal it and hence profit out of it. So the americans re-invented it a decade later and the rest is history.

If ever a country was lions led by donkeys its Britain.

More likely "tenth!" or just "not first!"

Re: Resources

"Thankfully its good to see that GCHQ have the common sense to put resources behind what is going on now and that should always be the case!"

Erm... they haven't. Someone spent ten minutes knocking up a statement saying "It's one-time pad, can't be broken without the code book, end of story"

How exactly is that ploughing resources into it?

"decided not to publicly reveal how its intelligence services were using cryptography."

Fixed that for you!

Get a brain then get a clue for it. You might as well ask who would have benefited from computers in 1973.

Re: Resources "Yet another non-related reply to the first comment from LarsG" Had you......

It is. It really, really is.

That's a phenomenal misread. You have essentially completely agreed with the person to whom you are replying, but whilst thinking you're disagreeing.

security by obscurity

Cryptography was considered by this culture something to be kept secret as it was thought your enemy would then find it harder to break. They were aware enough in the seventies of Kerckhoff's Law in relation to the requirement to be able to rekey a system in case an enemy learned a security system design, so by rekeying the hardware implementing this cipher could remain secure, but this came from a culture where non-disclosure of system design was genuinely believed to keep a system secure for longer than would otherwise be possible. The Bletchley Park WW2 Enigma crack was still kept secret until the late seventies and there was a cold war on, because the captured Enigma hardware had been sold on, to new customers who were assured it was still secure and upon whom the UK intended to spy.

Yes it's a very real shame in many ways that such important discoveries were sat on and languished unused - or used little as a consequence. But not publishing Clifford Cocks' public key system until 1997 didn't have such a negative effect on the development of British computing as keeping the Bletchley Park work under wraps did until the seventies. Even so, the more widely usable parts of the Bletchley Park work were reinvented in UK academic and commercial circles - at the cost of a significant few years of development, enabling IBM to capture most of the early computing market.

Raymond's Law: "given enough eyeballs, all bugs are shallow" adopted by the NSA when the SELinux Mandatory Access Control patch was contributed to the Linux community, and the understanding that cryptographic systems were best selected following public peer review e.g. as with the AES design competition, would take another 20 years or so to be widely adopted as the more sound engineering practice.

Only is you assume the first post wasn't sarcasm. Which is clearly was.

No: it says "Send three and fourpence, were're going to a dance"

Re: And these idiots at GCGQ are going to ...

"And these idiots at GCGQ are going to ... defend Britain from ne'er do wells? Capture spies and potential bomb tossers?"

What exactly is your point? They've been doing a pretty good job to date and have caught quite a lot of them.

If your point is that GCHQ are inept because they aren't spending the time to crack what should surely be an 'easy' 70 year old piece of code, then you really shouldn't be speaking so candidly about it, because you're not making yourself look clever at all.

The message was encrypted using a one-time pad, and the ONLY way to break a one-time pad is to have the pad or for the generation methods of the pad to be insecure in the first place. That's rather the point of them and why one-time pads are still secure and that's why they were used, and still are.

http://en.wikipedia.org/wiki/One-time_pad

Any muppet can construct trite backronyms for 30% of the message and ignore the other 70%, or even just make up a message. That's not decrypting it: It's making sh1t up. You can plug a super-computer into it and it will churn out an infinite number of 'possible' messages, but the only way of actually sussing it is by using the pad.

Re: And these idiots at GCGQ are going to ...

Or, to use a word that cropped up in an article here on the Reg just a few days ago, niggardly.

Oohhh. Controversial!

I fear I might be cruisn for another bruisn :(

With apologies to "Helping Children Through Research And Development"

When everyone can open my mental Encyclopedia (nicely to allow requisite shouting) all really easy parts require ten Toms yodeling. Sadly, help is the hardest of the ways humans equate natural interests there. Certainly others might eat some, tasting only mushrooms, apples, kale, interesting noodles, goldfish, and certain roots. Otherwise nothing you might see shall open minds. Every time I make ethanol someone tells Hubert "evolution yes!" Eventually varieties endanger news makers and keep everyone sane. "Enough nonsense," says everyone.

Not sure that makes any sense though...

Also AOAKN occurs twice in the message. Why would anyone send the same thing twice in a message?

But it's about WWII anyway?

Re: Ludicrous

Its not PABLIZ either, if you look at the pic on the BBC page it's clearly PABUZ . The groups of letters are always groups of 5 not groups of 5 and occasionally 6.

The message was written by a man who wrote his U's in a blocky form. Look at other parts of the message.

Re: Does it mean anything?

"Was this the style of such messages?"

Quite the opposite: If you are conveying important information via a pair of pigeons you've been carrying, you make darned sure that it's useful information!

What the article doesn't really note is the guy only 'decrypted' [cough] less than half the message. You'd assume that if he was correct that the missing parts would be grid references, encrypted via one-time pad... which STILL makes absolutely FA sense: The key thing about crucial communications is that they must be crystal clear. And mixing a smattering of ad hoc acronyms based on outdated 30 year old ones is going to simply confuse the hell out of the recipient, who has never met you or knows of your annoying habit of totally ignoring standard practice, and wonders if you've got your pad open on the right page, or if you've been captured and this is 'Jerry' ineptly passing misinformation.

Re: Panzer in a WW 1 Handbook ???

"I thought the term "Panzer" originated in WW2."

Ummm... no. It means 'armour', so kinda pre-dates that by several hundred years! The first German vehicle called a 'Panzer' [the Panzer 1] was fielded in 1932. However, the word was also being tossed around by German military thinkers and theorists by that time.

But yeah... it's still a pile of rubbish. And 'Panzer blitz'?! Seriously? As opposed to Blitzkrieg attacks NOT being spearheaded by armour?!? /facepalm.
