eclib 1.0.1

Encrypted Control library

ECLib

This is a Python library for numerical simulation of encrypted control.

Encrypted control

Cybersecurity is a critical issue of networked control systems in a modern society. Encrypted control is a novel concept of control using cryptographic tools for secure computation, such as homomorphic encryption and secret sharing. A control input in an encrypted control system is computed with encrypted data to improve the confidentiality of control systems. ECLib helps researchers and students to implement their new idea of encrypted control.

Install

You can use pip.

pip install eclib
