Nope I didn't miss that. Chosen Ciphertext or
Known Plaintext attacks
might still proof some valueable points. Actually otherwise this would be
less interesting.
Well, yeah but how would you get chosen / known plaintext ?
You can't really buy equipment that has TEA support in theory, its
distribution is limited.
Finding TETRA stuff is already not trivial, but finding some that has TEA
is even harder.
It's sometime possible to find just the FW files from some "shady
connections", but it's unclear if they'd work or if they depend on some HW
feature and at > 200 eur per handset not many people are ready to risk
bricking them for experiments :p
And even then you often don't control enough to know / choose what it sends.
Definitely quite a challenge :) But yeah can be fun if you can afford it.
Cheers,
