Massa is one of the only prominent drivers on the circuit still waiting to have a seat confirmed for 2013.
The Brazilian has insisted that he is not allowing the uncertainty to affect his performances after picking up points in his last five races.
He told Spanish newspaper Marca: "There's life after everything, but there's still life at Ferrari for the time being, which is what I want and am fighting for.
"When you haven't got a contract for the following year, that's always a big priority. We'll work on that, but the results, the race, what you do out on the track, are the most important thing."
Massa qualified in sixth place for Sunday's Korean Grand Prix, with teammate Alonso having to settle for fourth in his quest to win the world championship.
