About Keys and Certificates 415

About Keys and Public-private key pairs and digital signatures and certificates allow keys

Certificates to be generated dynamically so that data can be securely encrypted and delivered. You generate the key pairs and certificates on the WX switch or install them on the switch after enrolling with a certificate authority (CA). The WX switch can generate key pairs, self-signed certificates, and Certificate Signing Requests (CSRs), and can install key pairs, server certificates, and certificates generated by a CA.

The WX switch uses separate server certificates for Admin, EAP (802.1X), and WebAAA authentication. Where applicable, the manuals refer to these server certificates as Admin, EAP (or 802.1X), or WebAAA certificates respectively.

When the WX switch needs to communicate with 3Com Wireless Switch Manager, Web Manager, or an 802.1X or WebAAA client, MSS requests a private key from the switch’s certificate and key store:

„If no private key is available in the WX switch’s certificate and key store, the switch does not respond to the request from MSS. If the switch does have a private key in its key store, MSS requests a corresponding certificate.

„If the WX switch has a self-signed certificate in its certificate and key store, the switch responds to the request from MSS. If the certificate is not self-signed, the switch looks for a CA’s certificate with which to validate the server certificate.

„If the WX switch has no corresponding CA certificate, the switch does not respond to the request from MSS. If the switch does have a corresponding CA certificate, and the server certificate is validated (date still valid, signature approved), the switch responds.

If the WX switch does not respond to the request from MSS, authentication fails and access is denied.

For EAP (802.1X) users, the public-private key pairs and digital certificates can be stored on a RADIUS server. In this case, the WX switch operates as a pass-through authenticator.
