IGC-approval levels for some types of Flight Recorders

As I know every unit has it's own unique key (at least should). So if
you manage to open a logger box without clearing the key, you can create
fake logs only for that unit.

So let's say Snake is rich enough to afford two Alices.

done the dirty deed.


and therein lies the problem with relying on this type
of security alone. The strength of RSA is that the
private (secret) key cannot be deduced from the public
key, well not easily. The weakness is that once you
have got the private (secret) key then all the units
that use that key are obsolete. Whoops. So if snake
gets the private key and publishes it on here then
all the units that use that key are insecure.
