  The strange particle production off the nucleon induced by neutrinos and
antineutrinos is investigated at low and intermediate energies. We develop a
microscopic model based on the SU(3) chiral Lagrangian. The studied mechanisms
are the main source of single kaon production for (anti)neutrino energies up to
1.5 GeV. Using this model we have also studied the associated production of
kaons and hyperons. The cross sections are large enough to be measured by
experiments such as MINER$\nu$A, T2K and NO$\nu$A.
