The Security Industry Association (SIA) announced the Open Supervised Device Protocol (OSDP) with Data Security Extension as a new Standards Department project within the organization’s American National Standards Institute (ANSI) accredited standards program.

OSDP was originally developed by HID Global and Mercury Security Corporation (with some recent contribution from Codebench Inc.) as a communication protocol for interfacing peripheral devices, like card readers, to control panels or other security management systems. The SIA version will support both IP communications and point-to-point serial interfaces such as RS-485. The serial version of the protocol has been fully adopted by manufacturers and others are in the development stages of implementation.

SIA Standards chairman Steve Van Till said SIA plans to review the current version of OSDP through its normal committee process, which includes a public comment period. In addition to the review of the serial version, SIA will work toward extending the protocol for IP transport to ensure that the implementation needs of the majority of the industry are met.
