PAN encryption via Dukpt encryption


PAN encryption via Dukpt encryption

 
A POS Device Integration architect has the option sending the PAN to the iVeri Gateway in an encrypted format. This optional functionality is there as an extra security measure against someone sniffing the data between the device and the server communicating with the iVeri Gateway.

The Dukpt PAN encryption process flow is the following: A Device (with a DeviceSerialNumber and a DeviceMake) is injected in a Trusted Centre with a Track2 IPEK (initial pin encryption key). This IPEK is different from the one injected for Dukpt PIN encryption. For this encryption, the following are mandatory input parameters together with the PAN tag:

  1. DeviceSerialNumber
  2. DeviceMake
  3. PANKeySerialNumber
