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. TheWeb Server E-Mail Streaming

certificates can be shared by the services.

2N Helios IP

accepts the DER (ASN1) and PEM certificate formats.

Upon the first power up, the intercom automatically generates the Self Signed

for the and without forcing you tocertificate and private key Web Server E-Mail

load a certificate and private key of your own.

Refer to the tables below for the current list of trusted and user certificates:

Note

If you use the Self Signed certificate for encryption of the intercom web

server – browser communication, the communication is secure, but the

browser will warn you that it is unable to verify the intercom certificate

validity.
