The document doesn't seem to say that it's trying to reach a 128
bit security level over the whole chain. It seems to be happy
with 2048 bit RSA keys. They also provide 112 bit security.
If you really want to go for 128 bit, you need to have the RSA
keys of at least something in the order of 3072 bit. If 2048
is fine, 3DES is fine.
