Public key infrastructure secures IoT by enabling certificate-based authentication, ensuring trusted communication between devices.
Public key infrastructure (PKI) plays a crucial role in securing the Internet of Things (IoT) by offering a framework for managing digital certificates used for authentication and encryption. With PKI, each IoT device is assigned a unique public-private key pair. The device’s public key is shared with other devices or servers, allowing secure communication and data exchange. When a device needs to authenticate itself, it presents its digital certificate signed by a trusted certificate authority, validating its identity and ensuring secure interactions within the IoT ecosystem.
