Generating new How can I generate a Koblitz curvescurve?

isIs there the way how to generate new Koblitz curves (over, over F2n$\mathbb F_{2^n}$ and Fp as well)$\mathbb F_p$? I found that "The recommended parameters associated with a Koblitz curve were chosen by repeatedly selecting parameters admitting an efficiently computable endomorphism until a prime order curve was found."

The hereCerticom SEC 2 standard. says:

The recommended parameters associated with a Koblitz curve were chosen by repeatedly selecting parameters admitting an efficiently computable endomorphism until a prime order curve was found.

What meansdoes "efficiently computable endomorphism" mean? Maybe it means that trace of the Frobenius map should be equal 1? I am confused about all the Frobenius maps, endomorphisms, traces, etc.

So, is there the way to generate Koblitz curves (or compute efficient endomorphism), or find efficiently computable endomorphisms?

Thanks a lot for every advice.
