Abstract
A bundle of public counters and a corresponding bundle of private counters are created and transmitted to a user device. The user device receives a request and processes the request without accessing a secure element processor on the user device. The user device calculates a security code using the private counter and a number. The user device transmits the calculated security code and one of the bundle of public counters in response to the request. A receiver of the response to the request determines the validity of the public counter and looks up the corresponding private counter using the public counter. The receiver determines the validity of the security code by recomputing it using the private counter and the number.
