Two-Round Man-in-the-Middle Security from LPN

  title={Two-Round Man-in-the-Middle Security from LPN},
  author={David Cash and Eike Kiltz and Stefano Tessaro},
Secret-key authentication protocols have recently received a considerable amount of attention, and a long line of research has been devoted to devising efficient protocols with security based on the hardness of the learning-parity with noise (LPN) problem, with the goal of achieving low communication and round complexities, as well as highest possible security guarantees. In this paper, we construct 2-round authentication protocols that are secure against sequential man-in-the-middle (MIM… CONTINUE READING
