Although that would probably need to be higher grade to work. Technically it would be the better name.

The best advertisement for me was that terrorists use Telegram and Russia wants to ban it.

According to several world powers, the encryption terrorists use is superior and warrants further pro-surveillance legislation.

What is funny is that some powers that be really want backdoors in current crypto, because of course terrorists are stupid and will use backdoored crypto just like the rest of us.

Seems like they still do consider strong crypto to be just like munitions, because they seem to think if you just make it illegal then the gargantuan black market supply will just dry up and ordinary citizens won't be disadvantaged.

Plus the stakes are high in the military. If encryption fails, missions may be compromised and people die.

The stakes can indeed be high. However risk exposure (impact multiplied by probability) is often less than people think. An operational order betraying a strategy, for example "take Wimbledon Common at 4am tomorrow," must remain secret only until the order is carried out. So (gross simplification) any encryption that takes longer than from now to 4am tomorrow to break will suffice.

The harder problem is guaranteed delivery, which is impossible using only technology. You might email that order to the General in charge, and if he's out on a toke and doesn't read it within 5 minutes forward the order to his 2IC. And if the 2IC is on the john your only recourse is to forward the message to the nearest permanently staffed guaranteed action point (GAP). The GAP will send out one or more despatch riders to hunt the recipients down in meat space and deliver the message.

In any other scenario the same security best practices apply as in the commercial world, albeit with much more money.

Edited for spelling.

I tried googling "permanently staffed guaranteed action point (GAP)." With no results.

Is this the militarys mitigation of the two generals problem?

It's more like reliable messaging (say TCP over IP) as opposed to best-effort messaging (where no guarantee of delivery exists). Best-effort messaging better describes a solution to the two generals problem.
