The newest series of readers and credentials by PDK, Red Readers, utilize a high-security protocol known as Open Supervised Device Protocol, or OSDP, in addition to older Wiegand communications.
What Is OSDP?
This protocol is known as "high security" because it meets Federal Identity, Credential, and Access Management (FICAM) guidelines. It supports high-end, AES-128 encryption, which is required in federal government applications.
The key benefits of OSDP are listed by the Security Industry Association (SIA):
- Higher security
- Advanced functionality
- Ease of use
- More interoperability
Many organizations are slowly starting to replace perimeter readers first with OSDP-compatible readers, slowly moving to interior readers.
OSDP is basically an access control communications standard developed by the SIA to improve interoperability between access control and other security devices.
Benefits of OSDP
1. Higher Security
OSDP is more secure than most communications protocols between devices. It supports high-end, AES-128 encryption and constantly monitors wiring to protect against attack threats.
2. Advanced Functionality
OSDP supports the most advanced smartcard applications, like PKI/FICAM and biometrics. It also supports bi-directional communications between devices and advanced user interfaces, like text messages. Also, because it only uses 2 wires, OSDP allows for scalability to connect many field devices.
3. Ease of Use
OSDP encryption and authentication are predefined, which eliminates a lot of the guesswork. Also, OSDP is rather inexpensive to implement.
4. More Interoperability
Perhaps the biggest value proposition of OSDP is the fact that it allows communication between devices by various manufacturers. OSDP standard also applies to peripheral devices (i.e., readers, credentials).
