Privacy-Preserving Compute

FHE Hardware Accelerator

Dedicated hardware acceleration for fully homomorphic encryption, enabling computation on encrypted data without ever decrypting it. Process sensitive information in untrusted environments while maintaining complete mathematical privacy guarantees.

Compute on Ciphertext

Perform arbitrary computations on encrypted data without decryption. The data owner retains sole access to plaintext while the compute provider processes only ciphertexts and produces encrypted results.

Hardware Polynomial Engine

Dedicated large-degree polynomial multiplication engine purpose-built for the massive polynomial rings used in FHE. Orders of magnitude faster than software implementations for practical encrypted computation.

Multiple Schemes (CKKS/BFV/BGV)

Supports three leading FHE schemes: CKKS for approximate arithmetic on encrypted real numbers, BFV and BGV for exact arithmetic on encrypted integers — covering the full range of privacy-preserving workloads.

Core Capabilities

  • Three leading FHE scheme support: CKKS (approximate), BFV (exact), BGV (exact with modulus switching)
  • Hardware polynomial engine for large-degree multiplication (up to degree 65,536)
  • Dedicated bootstrapping acceleration for unlimited computation depth
  • Hardware key-switching engine for efficient post-multiplication operations
  • Parallel arithmetic channels for multi-precision modular operations
  • Intelligent memory management for large ciphertext working sets
  • High-bandwidth data interface for ciphertext input/output
  • Pipelined arithmetic units with configurable parallelism
  • Ciphertext packing and batched plaintext slot operations

Supported Operations

  • Homomorphic Addition (ciphertext + ciphertext, ciphertext + plaintext)
  • Homomorphic Multiplication (ciphertext × ciphertext, ciphertext × plaintext)
  • Rotation for batched operations
  • Key Switching / Relinearization
  • Modulus Switching / Rescaling (noise management)
  • Bootstrapping (full noise refreshing for unlimited depth)
