FPT: a Fixed-Point Accelerator for Torus Fully Homomorphic Encryption. (arXiv:2211.13696v1 [cs.CR])

Fully Homomorphic Encryption is a technique that allows computation on
encrypted data. It has the potential to drastically change privacy
considerations in the cloud, but high computational and memory overheads are
preventing its broad adoption. TFHE is a promising Torus-based FHE scheme that
heavily relies on bootstrapping, the noise-removal tool that must be invoked
after every encrypted gate computation.

We present FPT, a Fixed-Point FPGA accelerator for TFHE bootstrapping. FPT is
the first hardware accelerator to heavily exploit the inherent …
