  Recent investigations have shown that the sum secure degrees of freedom of
the Gaussian wiretap channel with a helper is $\tfrac{1}{2}$. The achievable
scheme for this result is based on the real interference alignment approach.
While providing a good way to show degrees of freedom results, this technique
has the disadvantage of relying on the Khintchine-Groshev theorem and is
therefore limited to {\it almost all channel gains}. This means that there are
infinitely many channel gains, where the scheme fails. Furthermore, the real
interference alignment approach cannot be used to yield stronger constant-gap
results. We approach this topic from a signal-scale alignment perspective and
use the linear deterministic model as a first approximation. Here we can show a
constant-gap sum capacity for certain channel gain parameters. We transfer
these results to the Gaussian model and discuss the results.
