5.6.5 Certificates
Some2N IPintercom network services use the Transaction Layer Security (TLS) 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
Sets of CA certificates can be uploaded to the2N IP intercoms, which are used for identity
verification of the device that the intercom is communicating with, and also 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Web Server,E-MailandStreamingsubsections. The certificates can be shared by the
services.
2N IPintercom accepts the DER (ASN1) and PEM certificate formats.
2N IP intercomsupports the AES, DES and 3DES encryption.
2N IP intercomsupports the following algorithms:
