8 Certificate Management

Certificates can be used in TCP/IP-based networks to encrypt data and to authenticate communication partners. Certificates are electronic messages containing a key (public key) and a signature.

Certificates increase security. Use certificates on your TPG60

•to receive encrypted print data; see: ’How Does the TPG60 Receive Encrypted Data?’ Ö53.

•to check the identity of the TPG60 in the network; see: ’How

Does the TPG60 Authenticate Itself in the network via EAP-TLS?’ Ö60.

If you want to use certificates, it is advisable to protect the TPG60 by a password so that certificates cannot be deleted by unauthorized persons; see ’How to Protect the TPG60 against Unauthorized Access? (Password Control)’ Ö55.

Both self-signed certificates and CA certificates can be used in the TPG60. The following certificates can be distinguished:

Self-signed certificates have a digital signature that has been created by the TPG60. If a self-signed certificate is used, the ThinPrint® server cannot print via SSL. A CA certificate is mandatory to print via SSL.

CA certificates are certificates that have been signed by a certification authority (CA).

The authenticity of the CA certificate can be verified by means of a so-called root certificate issued by the certification authority. The root certificate is stored on an authentication server in the network.

Upon delivery, a self-signed certificate (the so-called default certificate) is stored in the TPG60. It is recommended that you replace the default certificate by a self-signed certificate or CA certificate as soon as possible.
