France is committed to "destroying" the so-called Islamic State group after Friday's deadly attacks, President Francois Hollande has said.
He said he would table a bill to extend the state of emergency declared after the attacks for three months and would suggest changes to the constitution.
France's military campaign against IS in Iraq and Syria will also intensify.
IS says it carried out the attacks on bars, restaurants, a concert hall and a stadium in which 129 people died.
Speaking during a joint session of both houses of parliament, Mr Hollande said the constitution needed to be amended as "we need an appropriate tool we can use without having to resort to the state of emergency".
Other measures he said would be pursued included:
5,000 extra police posts in the next two years and no new cuts in the defence budget
Making it easier to strip dual nationals of their French citizenship if they are convicted of a terrorist offence, as long as this did not render them stateless
Speeding up the deportation of foreigners who pose "a particularly grave threat to the security of the nation"
Pushing for greater European action against arms trafficking and greater penalties for it in France.
