Open Supervised Device Protocol (OSDP)
|
|
######################################
|
|
|
|
Open Supervised Device Protocol (OSDP) is an IEC standard (IEC 60839-11-5)
|
|
intended to improve interoperability among access control and security products.
|
|
It supports Secure Channel (SC) for encrypted and authenticated communication
|
|
between configured devices.
|
|
|
|
OSDP describes the communication protocol for interfacing one or more Peripheral
|
|
Devices (PD) to a Control Panel (CP) over a two-wire RS-485 multi-drop serial
|
|
communication channel. Nevertheless, this protocol can be used to transfer
|
|
secure data over any stream based physical channel. Read more about `OSDP here
|
|

|
|
|
|
Although OSDP is steered towards the Access and Security industries, it can be
|
|
used as a general communication protocol for devices in a secure way without
|
|
too much resource requirements. The security is not top-notch (AES-128) but it
|
|
is reasonable enough, given that the alternative is no security at all.
|
|
|
|
OSDP Supports the control of the following components on a PD:
|
|
- LED
|
|
- Buzzer
|
|
- Keypad
|
|
- Output (GPIOs)
|
|
- Input Control (GPIOs)
|
|
- Displays
|
|
- Device status (tamper, power, etc.,)
|
|
- Card Reader
|
|
- Fingerprint Reader
