Patent ID: 8036378

Claim:
A method of authentication, the method comprising: sharing an initial state value S( 0 ) from a sender with a receiver; generating a sender S(t, v) from S( 0 ) based on a parameter t and an identifier v via an updater function derived from a solution to a stochastic differential equation, wherein the updater function includes steps comprising: setting S equal to S( 0 ); setting W t equal to G(v); performing, at each iteration in a loop of t−1 iterations, steps comprising: setting S equal to S*K((μ−(σ 2 )/2)+σ*W t ); setting W t equal to W t +G(L(W t )); and returning S, wherein (1) G(v) performs a splitting operation, Hamming weight computation and enlarging of a reparation of v and (2) L( ) is one of an encryption and a hash function; receiving a receiver S(t, v) generated from S( 0 ) based on the parameter t and the identifier v; and authenticating the identifier v based on a comparison of the sender S(t, v) and the receiver S(t, v).
