8 Certificate Management
What are
Certificates?
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.
How to Use
Certificates?
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.
Which Certificates
are available?
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.
