Abstract
Fully homomorphic encryption integrated circuit (IC) chips, systems and associated methods are disclosed. In one embodiment, an integrated circuit (IC) homomorphic processor chip is disclosed. The IC homomorphic processor chip includes at least one processor slice. Each processor slice includes local control circuitry, a numeric theoretic transform (NTT) butterfly unit, and on-chip memory. The NTT butterfly unit is responsive to the local control circuitry to operate in multiple modes for performing operations on encrypted data using homomorphic encryption. Each mode is associated with a different configuration of the NTT butterfly unit.
