Abstract:
Example embodiments of systems and methods for data transmission between transmitting and receiving devices are provided. In an embodiment, each of the transmitting and receiving devices can contain a master key. The transmitting device can generate a diversified key using the master key, protect a counter value and encrypt data prior to transmitting to the receiving device. The receiving device can generate the diversified key based on the master key and can decrypt the data and validate the protected counter value using the diversified key.
