How does a Certificate Authority work?

Back to Wiki

A Certificate Authority usually operates in hierarchies where a Root CA certifies itself (self signed) and a subordinate CA is certified (signed) by a superior CA. Most Certificate Authority software solutions work with standard interfaces and protocols so that interoperability can be guaranteed.

A Certificate Authority works together with a Registration Authority where the RA issues a certificate request to the CA via a user-friendly GUI or via integration friendly APIs and standard protocols.

PrimeKey offers an industry-first solution, Identity Authority Manager, for implementing an RA directly into a smart manufacturing environment.
