Published October 2018.
Introduction
Mosaic Connect is a wireless presentation solution allowing individual connected devices to share their screen to a large format
display. Mosaic Connect is available on multiple platforms:
● Windows software, available for Windows 10. This allows the Mosaic Connect software to be deployed securely across
existing hardware.
Note: features vary per platform
Infrastructure
All inbound and outbound data from our backend layer is encrypted and transmitted over TLS or DTLS with 2048-bit asymmetric
encryption and 256-bit symmetric encryption using certificates from third party credited authorities. Network communication is
protected using the latest in technology to secure all video, audio and data.
Using the TLS and DTLS cryptography protocols, previously referred to as SSL, we provide protection using a 2048-bit
asymmetric key in conjunction with a 256-bit symmetric session key. More information on network ports used can be found
further within this document.
The backend tier provides four public services; REST API, XMPP and STUN / TURN.
We use a combination of both Azure and Amazon services to provide a resilient and redundant backend whilst providing the
lowest latency possible.
