CiFHER: A Chiplet-Based FHE Accelerator with a Resizable Structure. (arXiv:2308.04890v1 [cs.AR])

Fully homomorphic encryption (FHE) is in the spotlight as a definitive
solution for privacy, but the high computational overhead of FHE poses a
challenge to its practical adoption. Although prior studies have attempted to
design ASIC accelerators to mitigate the overhead, their designs require
excessive amounts of chip resources (e.g., areas) to contain and process
massive data for FHE operations.

We propose CiFHER, a chiplet-based FHE accelerator with a resizable
structure, to tackle the challenge with a cost-effective multi-chip module …
