Usage

To generate a set of keys into the folder <SECRET_KEY_PATH>:

cargo run -- keygen <SECRET_KEY_PATH>

To encrypt the plaintext stored in file <PLAINTEXT_INPUT_PATH> using the set of keys stored in folder <SECRET_KEY_PATH> and write the resulting ciphertext into the file <CIPHERTEXT_OUTPUT_PATH> (not implemented):

cargo run -- encrypt <SECRET_KEY_PATH> <PLAINTEXT_INPUT_PATH> <CIPHERTEXT_OUTPUT_PATH>

To evaluate the model stored in file <MODEL_PATH> for the ciphertext input stored in file <CIPHERTEXT_INPUT_PATH> using the evaluation key stored in folder <EVALUATION_KEY_PATH> and write the encrypted model output into the file <CIPHERTEXT_OUTPUT_PATH> (not implemented):

cargo run -- inference <EVALUATION_KEY_PATH> <MODEL_PATH> <CIPHERTEXT_INPUT_PATH> <CIPHERTEXT_OUTPUT_PATH>

To decrypt the ciphertext stored in file <CIPHERTEXT_INPUT_PATH> using the set of keys stored in folder <SECRET_KEY_PATH> and write the resulting plaintext into the file <PLAINTEXT_OUTPUT_PATH> (not implemented):

cargo run -- decrypt <SECRET_KEY_PATH> <CIPHERTEXT_INPUT_PATH> <PLAINTEXT_OUTPUT_PATH>

To show how the program or a specific command is used:

cargo run -- --help
cargo run -- <COMMAND> --help

Evaluation

Setup

• Install Rust and Cargo: curl https://sh.rustup.rs -sSf | sh
• Install Python (3.9)
• Install Python dependencies: pip install argparse pathlib numpy tqdm

Run evaluations

• cd evaluation
• Run evaluation: python benchmark.py -m cryptonets (Attention: This evaluation may take several minutes to hours!)
• Parameters:
  • -m: model [cryptonets, lenet5 (default), mobilefacenets]
  • -s: start-index of samples, default: 0
  • -n: number of samples, default: 10
