Public Key Infrastructure (PKI) is a system used to establish a secure and trusted digital identity for IoT (Internet of Things) devices. It ensures secure communication by using certificates for authentication. Certificates are issued to devices, each containing a public key and other identifying information, allowing for encrypted communication between devices and confirming their identity on a network. This helps prevent unauthorized access and ensures the integrity of data transmitted between IoT devices.
