Bent functions on partial spreads.
Designs, Codes and Cryptography 73 (2014), 209-216.
For an arbitrary prime p we use
partial spreads of Fp2m to construct
two classes of bent functions from Fp2m
to Fp.
Our constructions generalize the classes PS(-) and PS(+)
of binary bent functions which are due to Dillon.
