Buying a Certificate from CA

PKI for IoT

A public CA is a third-party entity that issues certificates for a fee after doing the necessary checks on the organization requesting a certificate. The checks by default include domain validation, and Third-party CAs have their own public-private key pairs with which they sign the certificates. Most of the well-known CAs are recognized by servers and clients; therefore, certificates signed by them are immediately validated by the entity initiating a secure connection. Publicly-signed certificates offer a higher level of assurance since they are issued by a recognized CA, and are generally used for securing websites and other endpoints involving direct user interaction.
