HHR-4X66 Single-lane Kits - Wireless Encryption
OSDP Secure Channel Encryption:
The HHR-8066 reader has its own OSDP Secure Channel
session with the HHR-8300/HHR-8400 base. Each of
these OSDP Secure Channel sessions is encrypted with
its own encryption key.
Radio Level Encryption:
The radios in all of the HHR-8066 readers and the
HHR-8300/HHR-8400 base encrypt all of data being
transmitted between the readers and the base. The radio
level encryption uses AES128. The readers and the base
share an encryption key for the radio level encryption.

Wireless Communication
The wireless radios in the HHR-4000 readers and base units use the IEEE 802.15.4 standard for mesh networking. The
HHR readers and base units form ad-hoc mesh networks, which do not require additional external infrastructure (such
as WLAN) to function.
The communication protocol between HHR-4000 devices over the air is the Open Supervised Device Protocol (OSDP).
OSDP is an IEC standard (IEC 60839-11-5). This protocol uses the AES-128 cipher in CBC mode for both data
confidentiality and message authenticity.
Wireless Encryption
The HHR-4000 devices wireless communication utilize two layers of encryption. The first layer of encryption is on the
radio link layer, which uses AES-128 to encrypt data packets between the radios in the Handheld readers and the Base
Unit. The second layer of encryption is on the protocol level, which uses the OSDP Secure Channel protocol to encrypt
the OSDP messages sent between the Base Unit and the Handheld Readers.
