Abstract

A proposal for BACnet secure messaging is nearing public release by the BACnet standard committee (ASHRAE SSPC-135). The proposal adds a level of BACnet specific security to existing IT security, extending the BACnet standard to offer basic security using signatures for integrity protection, and higher security with encryption for confidentiality. An introduction to the BACnet Security proposal is presented.
