Bent functions have many important applications in cryptography and coding theory. This paper considers a class of
$ p $
-ary functions with the Dillon exponent of the form
$ f(x) = \sum\limits_{i = 0}^{q-1}(Tr^n_1(a_1x^{(r i+s)(q-1)})+Tr^n_1(a_2x^{(r i+s)(q-1)+\frac{q^2-1}{2}}))+bx^{\frac{q^2-1}{2}}, $
where
$ n = 2m $
,
$ q = p^m $
,
$ p $
 is an odd prime,
$ a_1,a_2\in \mathbb{F}_{p^n} $
, and
$ b\in \mathbb{F}_p $
. With the help of Kloosterman sums, we present an explicit characterization of these
$ p $
-ary regular bent functions for the case
$ gcd(s-r,\frac{q+1}{2}) = 1 $
 and
$ gcd(r,q+1) = 1 $
 or
$ 2 $
. Our results generalize results of Li et al. [IEEE Trans. Inf. Theory 59 (2013) 1818-1831].
Keywords: p-ary regular bent functions, Walsh transform, Kloosterman sums, p-ary functions, bent functions.
