They don't so much backdoor the keying as that they have 4 different cipher profiles, and the one approved for global rather than European use (TEA1) compresses the key from 80 to 32 bits.

It's essentially a surreptitious version of what the US did in the 1990s with "export ciphers".

Which makes me question describing this as a "deliberate backdoor."

[tptacek]

It's pretty clearly a deliberate backdoor.

And that is supported by the known past actions of "some government authorities". This is definitely not the first time the US government has deliberately sabotaged crypto.

[tptacek]

This isn't an American product.

It's deliberate in making the crypto so weak that our guys can decrypt their guys' radio traffic.

How's that not a backdoor?
