Configuration Task Summary

Configuration Task Summary

After the PKI configurations are complete, the device can obtain the digital certificates for identity verification, data encryption, and data signing.

Table 15-2 lists the PKI configuration tasks. The device obtains certificates in one of the following ways. The certificates include CA certificates and device certificate. The device uses the device certificate to show its own identity, and uses the CA certificates to verify the validity of the device certificate.

Scenario

Description

Task

Applying for certificates

An entity submits the identity information to the CA server and obtains the certificates. In this process, the entity submits the identity information and public key to the CA server. The CA server adds the identity information and public key into the certificate issued to the entity. Depending on whether there is a reachable route between the device and CA server, two ways to apply for certificates are available:

  • Online: When a reachable route exists between the device and CA server, the device communicates with the CA server through SCEP to obtain certificates.

  • Offline: When no reachable route exists between the device and CA server, the user needs to manually generate a certificate request file on the device, and sends the file to the CA server through disk or email.

Importing certificates

The user imports the obtained certificates to the device memory. This mode is applicable when the user has bought certificates from the IAOPC or has obtained certificates from the CA server.

Importing a Certificate

Self-signed certificate

A self-signed certificate is issued by the device. That is, the certificate requester and issuer are the same. This mode is applicable when the user requires a temporary certificate or has low requirement on data security.

Creating a Self-signed Certificate or Local Certificate

To ensure that the encrypted data can be decrypted by the two parties, import the certificates to both the two parties. You can upload the certificates of the remote device to the storage device on the local device through FTP or TFTP, and then import the certificates to memory. Alternatively, you can open the certificate files, and copy the certificate contents on the screen to import the certificates to memory. For details about importing the certificates of the remote device, see Configuring the Device to Import or Release a Digital Certificate of the Remote Device.
