5.5.4 Certificates
Some
network services use the Transaction Layer Security (TLS)
2N Helios IP
®
protocol for communication with other LAN devices to prevent third parties from
monitoring and/or modifying the communication contents. Unilateral or bilateral
authentication based on certificates and private keys is needed for establishing
connections via TLS.
The following intercom services use the TLS protocol:
Web server (HTTPS)
E-mail (SMTP)
802.1x (EAP-TLS)
SIP
The
intercom allows you to load up to three sets of trusted certificates,
2N Helios IP
®
which help authenticate LAN devices for communication with the intercom, and three
sets of user certificates and private keys for communication encryption.
Each certificate-requiring service can be assigned one of the three certificate sets
available; refer to the
,
and
subsections. The
Web Server
Streaming
certificates can be shared by the services.
2N Helios IP
®
accepts the DER (ASN1) and PEM certificate formats.

and
without forcing you to
certificate and private key
Web Server
load a certificate and private key of your own.

Self Signed certificate for encryption of the intercom web
server – browser communication, the communication is secure, but the
