OSDP - Open Supervised Device Protocol¶
This is an open source implementation of Open Supervised Device Protocol (OSDP) developed by Security Industry Association (SIA). The protocol is intended to improve interoperability among access control and security products. OSDP is currently in-process to become a standard recognized by the American National Standards Institute (ANSI).
OSDP describes the communication protocol for interfacing one or more Peripheral Devices (PD) to a Control Panel (CP). The OSDP specification describes the protocol implementation over a two-wire RS-485 multi-drop serial communication channel. Nevertheless, this protocol can be used to transfer secure data over any physical channel. Have a look at the protocol design documents to get a better idea.
Salient Features of LibOSDP¶
Supports secure channel communication (AES-128).
Can be used to setup a PD or CP mode of operation.
Exposes a well defined contract though
No run-time memory allocation. All memory is allocated at init-time.
Well designed source code architecture.
