Abstract
An apparatus includes at least one linear feedback shift register and at least one processing device comprising a processor coupled to a memory. The at least one processing device is configured to obtain a given value from the at least one linear feedback shift register, the given value comprising a set of bits representing a current state of the linear feedback shift register. The at least one processing device is also configured to generate authentication information by applying the given value obtained from the at least one linear feedback shift register as input to a pseudorandom function, and to provide the generated authentication information to a validating application.
