I'm looking at the FIPS-186 standard. On page 88, it gives a table recommending the size of the base field for the elliptic curve versus the order $n$ of a point on the curve. The numbers don't seem to make sense. For example it says if the bit length of $n$ is between $161$ and $223$, then the bit length of the ambient finite field should be $192$. But if you go off these numbers, there's a good chance that $n$ will be bigger than the size of the elliptic curve group itself. For example, say $p \approx 2^{192}$ and the bit length of $n$ equals $223$. Then by Hasse's theorem, the number of points on the elliptic curve will be less than $2^{192} + 1 + 2^{96}$, which is much smaller than $n$.
Can someone explain to me what the table in the standard means?
