This is a most excellent place for technology news and articles.
Which had/has a built-in backdoor for years.

EU security forces didn't really care as TEA2 wasn't backdoored. It's a mid-90s standard with different encryption levels for different actors, it should be blindingly obvious that whatever is publicly available is backdoored. You may not like it, I do not like it, but it should've been obvious.
The actual own goal was that while all EU security forces always had access to the secure stuff plenty of operators of critical infrastructure (think energy suppliers etc) used TEA1 as that's what they were given. Also some EU forces bought TEA1 equipment presumably because they didn't know what they were doing, with or without help from manufactures with an overstock of TEA1 radios.
Here's a 37c3 talk about the whole thing, from the people actually breaching the protocol.
Aside from those encryption issues (which are finally getting addressed btw) TETRA is a great protocol, though. By now a bit dated so bandwidth isn't exactly stellar (forget video streaming or such) but devices can talk directly to another just as in olden times, setting up a base station simply increases range, radio channels are now virtual, it's all very sweet. Basically TETRA is to radio what GSM is to rotary phones. Which, as GSM phones don't tend to be wired, makes a hell a lot more sense.
Wait the CCC speaks English? I thought they were German!
Projecting a wee bit, aren't we?
Also the presenters are Dutch. The congress is bilingual though IIRC simultaneous translation is only in place for German->English.
CCC was founded in Germany. It's not strange to assume they'd publish in German.
Oh they do. And if it was a rabbit breeder association it would stand to reason that they'd only publish in German, but they aren't, and they don't.
Du hast mich gefragt!
