Certificates
Some 2N Indoor Talk LAN services use the secure TLS protocol for communication with the other LAN
devices. This protocol prevents third parties from eavesdropping on or modifying call contents. TLS is based
on one/two-sided authentication, which requires certificates and private keys.
The following device services use the TLS protocol:
1.
Web server (HTTPS)
2.
3.
802.1x (EAP-TLS)
4.
SIPs
The device allows you to upload up to 3 sets of certificates from certification authorities, which help you au-
thenticate the communicating device, and also 3 user certificates and private keys for encryption purposes.
Each certificate requiring service can be assigned one certificate set, refer to
certificates can be shared by the services.
The device supports the DER (ASN1) and PEM certificate formats.
Upon the first power up, the intercom automatically generates the Self Signed certificate and private key for
the Web server and services without forcing you to load a certificate and private key of your own.
NOTE
If you use the Self Signed certificate for encryption of the device web server – browser
communication, the communication is secure, but the browser will warn you that it is unable
to verify the device certificate validity.
The current list of uploaded CA and user certificates is available in the following two folders: CA Certificates
and User Certificates.
