Secure computation techniques — homomorphic encryption and multi-party computation — that let parties compute joint results without revealing their inputs. Central to industrial-grade frameworks such as [FATE](../frameworks/fate.md); computationally heavier than [secure aggregation](secure-aggregation.md) or [DP](differential-privacy.md).
