What is IoT PKI?

The Internet of Things Public Key Infrastructure is a security architecture that secures communications between IoT devices and other entities such as cloud servers, gateways, and other IoT devices by utilizing digital certificates and public key cryptography.

The PKI system includes a Certificate Authority (CA) that issues digital certificates to the entities involved in the communication, a Registration Authority (RA) that verifies the identity of the entities, and a Certificate Revocation List (CRL) that lists revoked certificates.

In the context of IoT, each IoT device is assigned a unique digital certificate, which is used to verify its identity during communication. This ensures only authorized devices can communicate with other entities within the IoT ecosystem.

IoT PKI provides high security and confidentiality to IoT communication by using advanced encryption techniques. Establishing mutual authentication, preserving data confidentiality, ensuring software integrity, and complying with privacy regulations are crucial to securing IoT adoption.
