8.15 Property 0x6B - Key Management Scheme (Fixed Key Only)

0x6B
Property ID:
Property Type: Byte
Length: 1 byte
Get Property: Yes
Set Property: Yes
Default Value: 0x00 (TDES DUKPT)
This property controls the key management scheme the device uses to generate keys to encrypt all data it
sends to the host. When this property is set to Fixed Key, the host must use Command 0x4E - Load
Fixed Key (Fixed Key Only) to load a 16-byte fixed key into the device. The device then uses the fixed
key to encrypt all encrypted data it sends to the host. All references in this manual to the current DUKPT
key should then be read to mean the single fixed key instead. For details about encryption, see section 5
Encryption, Decryption, and Key Management.
The possible values are:
•
0x00 = TDES DUKPT. The device uses the current DUKPT Key to encrypt data.
•
0x01 = Fixed Key. The device uses the current fixed key as-is (no variant) to encrypt data.
This property is stored in non-volatile memory, so it persists when the device is power cycled. When this
property is changed, the device must be reset (see Command 0x02 - Reset Device) or powered off for at
least 30 seconds, then powered on, before the changes will take effect.
