Each JACE within a Niagara network requires its own unique private key and signed server certificate, which is stored in its Key Store.

Each client within a Niagara network requires a copy of the CA (root) certificate used to sign the server’s certificate for any servers to communicate securely within the network. These certificates reside in the client Trust Store.

One certificate may be used to secure Fox station communication, Web Service and Niagarad or each service may have its own server certificate and pair of keys.

The number of certificates you need depends on the number of platforms in your network and the type of communication you need to secure.

For more on how many certificates you may need, see Design the certificate chain of trust.
