Abstract
The arrangements disclosed herein relate to systems, apparatus, methods, and non-transitory computer readable media for Quantum for DUKPT (Q-DUKPT), where an Initialization Key (IK) using a Quantum Random Number Generator (QRNG). An identifier for a device is generated by performing XOR on a Base Derivation Key (BDK) and the IK. The device derives a key for each transaction to encrypt original data using IK or a previous key. The host receives from the device the encrypted original, the identifier, and a counter that indicates a current number of transactions. The host runs the same derive function used by the device for a number of iterations equal to the current number of transactions with IK as the initial input, to derive the key used to by the device to encrypt the original data.
