SecureNN is an implementation from the SecureNN paper.
SecureNN is an extension of the Pond protocol. ie SecureNN is a superset of
the SPDZ protocol. The main difference between SecureNN and SPDZ is exact
Relu and Maxpooling layers.
In SPDZ, Maxpooling is simply not supported, and
will be approximated.
Approximation can be quicker in some cases but it will break down when inputs
are sufficiently large. This requires users to implement workaround techniques such
as adding a
Batchnorm layer before
