The Z-Wave network is designed to be secure and includes encryption as one of its key features. Z-Wave uses a proprietary wireless communication protocol that utilizes AES-128 encryption for secure communication between devices. This encryption helps prevent unauthorized access to the network and protects the privacy of data transmitted between devices.
In addition to encryption, Z-Wave also uses a unique network key for each installation, which further enhances security. This key is used to authenticate devices that want to join the network and prevent unauthorised devices from accessing the network.
Overall, Z-Wave's use of encryption and other security features makes it a secure choice for home automation and other applications.
