4 CrypTen
CrypTen is a secure multiparty computation framework introduced by B. Knott (2022). CrypTen is significant because it takes concepts which are well-established within the context of multiparty computation, and establishes an easy-to-use system which will feel familiar to researchers already know PyTorch. This is extremely important since the widespread adoption of secure computation techniques up to this point have largely been limited to (1) the complexity of primitives associated and (2) the low-level implementation used by most state-of-the-art systems such as Delphi and Cheetah.

In other systems such as Delphi, model encryption is treated as an issue of
