Structure of a typical BACnet/SC network
BACnet/SC
Encryption
and certificates
TCP (Transmission Control Protocol) and WebSocket – two reliable
mechanisms based on the internet protocol (IP) widely used in IT –
are used for secure data transmission. TCP/IP replaces the UDP
(User Data Protocol) network protocol layer previously used by
BACnet; TLS is used to ensure bug-proof and tamper-proof
communications. TLS (Transport Layer Security) is also widely used
as the foundation for secure internet access (https) in IT.
As far as encryption is concerned, a company-wide procedure must
be put in place for the necessary digital certificates.
The certification and registration authorities responsible for the
internet in connection with public key infrastructures are not
specified in BACnet/SC. This means building automation operators
can take account of their individual network structures.
