Split Secret Cryptography Based Security in IoT Implemented Payment Transactions or Credentials

The invention provides methods, systems and computer program products for securely provisioning an internet-of-things (IoT) device for implementing an electronic payment transaction. The invention comprises (i) retrieving a first credential element from the client device, and a second credential element from a router, (ii) generating payment credential data by applying split secret cryptography based reconstruction to the first credential element and the second credential element, (iii) retrieving a unique identifier associated with the IoT device, (iv) generating a combined data element comprising the payment credential data and the unique identifier associated with the loT device, (v) applying split secret cryptography based splitting to the combined data element to generate a first verifiable secure element and a second verifiable secure element, (vi) storing the first verifiable secure element and the retrieved unique identifier within the router, and (vii) storing the second verifiable secure element within the IoT device.
