eclib 2.0.0

Encrypted Control Library

ECLib

ECLib is an easy-to-use open-source homomorphic encryption library for encrypted control.

Supported encryption schemes

• ElGamal
• Dynamic-key ElGamal
• Paillier
• Regev (LWE)
• GSW
• GSW-LWE

Requirements

• Python 3.12.x
• NumPy
• Matplotlib
• python-control

Getting Started

1. Install ECLib.

   pip install eclib

2. Run example scripts.

Examples

• elgamal.py

  Basics of ElGamal encryption.

• dyn_elgamal.py

  Basics of Dynamic-key ElGamal encryption.

• paillier.py

  Basics of Paillier encryption.

• regev.py

  Basics of Regev (LWE) encryption.

• gsw.py

  Basics of GSW encryption.

• gsw_lwe.py

  Basics of GSW-LWE encryption.

• state_feedback.py

  Comparison of plant inputs and states between unencrypted and encrypted state-feedback controls. To run this script, you must specify an encryption scheme for encrypting a state-feedback controller, e.g., python state_feedback.py elgamal.

• pi.py

  Comparison of plant inputs and outputs between unencrypted and encrypted PI controls. Similar to state_feedback.py, you must specify an encryption scheme for encrypting a PI controller, e.g., python pi.py paillier.
