Authentication With a Guessing Adversary

In this paper, we consider the authentication problem where a candidate measurement presented by an unidentified user is compared to a previously stored measurement of the legitimate user, the enrollment, with respect to a certain distortion criteria for authentication. An adversary wishes to impersonate the legitimate user by guessing the enrollment until the system authenticates him. For this...

Hierarchical Guessing with a Fidelity Criterion

In an earlier paper, we studied the problem of guessing a random vector X within distortion D, and characterized the best attainable exponent E(D; ) of the th moment of the number of required guesses G(X) until the guessing error falls below D. In this paper, we extend these results to a multi-stage, hierarchical guessing model, which allows for a faster search of a codeword vector at the encod...
