The authentication process

1. A CA server provides the required signed certificates.
2. The Axis video device requests access to the protected network at the network switch.
The switch forwards the video device's CA certificate to the RADIUS server, which then
replies to the switch.
3. The switch forwards the RADIUS server's CA certificate to the video device, which also
replies to the switch.
4. The switch keeps track of all responses to the validation requests. If all certificates are
validated, the Axis video device is allowed access to the protected network via a
pre-configured port.
RADIUS
RADIUS (Remote Authentication Dial In User Service) is an AAA (Authentication,
Authorization and Accounting) protocol for applications such as network access or IP
mobility. It is intended to work in both local and roaming situations.
CA servers
In cryptography, a Certification Authority (CA) is an entity that provides signed digital
certificates for use by other parties, and thus acts a trusted third party.
There are many commercial CA's that charge for their services. Institutions and
governments may have their own CA, and there are free CA's available.
