Aug 16, 2019 at 12:08 comment added Ilmari Karonen Do you need resistance to forgery or other active (i.e. chosen-plaintext / chosen-ciphertext) attacks? And if so, what's an acceptable probability for a fake/modified ciphertext being accepted? (You can't really make it less than one in $10^7$ with your constraints, but that limit can be achieved.)
