FHE Average Computation Demo

Compute the average of encrypted numbers without ever decrypting them.

How it works

  1. Generate keys locally using the client-tools CLI
  2. Encrypt your data locally — numbers become a ciphertext file
  3. Upload the ciphertext to this platform
  4. Compute — the server computes the average on encrypted data (GPU-accelerated)
  5. Download the encrypted result
  6. Decrypt the result locally with your secret key

Upload Ciphertext

Upload an encrypted file for computation

Key Sets

Manage encryption key sets

Danger Zone

Verify results (demo only)

Quick Start with Demo Keys

# Install client-tools
cd fhe-tools-and-demos/client-tools
bash init/setup-venv.sh && source venv.sh

# Create test data
echo -e "1.5\n2.3\n3.1\n4.7" > data.txt

# Encrypt with demo keys
python -m client_tools encrypt --input data.txt --output ct.bin \
  --public-dir ./demo_keys/publickeys

# Upload ct.bin on the Upload page, then download the result

# Decrypt the result
python -m client_tools decrypt --input result.bin --output result.json \
  --secret-dir ./demo_keys/secretkey -n 4
