Homogeneous processing unit (HPU) for accelerated security calculations by homomorphic encryption

摘要

Fully homogeneous cryptographic integrated circuit (IC) chips, systems, and associated methods are disclosed. In one embodiment, an integrated circuit (IC) homogeneous processor chip is disclosed. The IC homogeneous processor chip includes at least one processor slice. Each processor slice includes a local control circuitry, a numerical theoretic transform (NTT) butterfly unit, and on-chip memory. The NTT butterfly unit operates in a number of modes to perform operations on data encrypted using homogeneous encryption in response to the local control circuitry. Each mode is associated with a different configuration of the NTT butterfly unit.
