Abstract
Disclosed herein are systems, methods and computer readable media for performing authentication. The proposed scheme utilizes new algorithms that introduce randomness using a physical value for authentication. An exemplary method includes sharing an initial state value S() with a sender and a receiver, generating a sender S(t, v) based on a parameter t and an identifier v and based at least in part on the value S(). The method includes generating a receiver S(t, v) from S() based on the parameter t and the identifier v wherein the parameter t is related to a physical value in authenticating the identifier v based on a comparison of the sender S(t, v) and the receiver S(t, v). The process of generating the sender S(t, v) and the receiver S(t, v) includes a random variable generated by a process such as by a random number generator, the Brownian Motion or Wiener Process. Other embodiments do not use the physical value for authentication.
