  We present the first K-band bispectrum speckle interferometry of NGC 1068
with an angular resolution of 76 mas (~5.5pc). This angular resolution allows
us to attribute the measured flux to only one of the nuclear sources seen at
radio wavelengths. The observed decreasing visibility function suggests that
the dominant central core is probably not an unresolved point source, but
slightly resolved with a FWHM diameter of ~30 mas ~2pc for an assumed Gaussian
intensity distribution. This 30 mas object is possibly the nuclear torus and/or
a scattering halo. We discuss different contributions to the observed K band
flux. Between 5 GHz and the K-band the spectrum of this component is close to a
nu^(1/3) proportionality. In addition to the standard interpretation of a hot
dust torus surrounding the nucleus of NGC 1068, one cannot exclude the
possibility that a sizeable fraction of the nuclear flux reaches us via a
scattering halo. This then would allow us to determine physical parameters of
the nuclear source.
