| Abstract(in English) | Password checking schemes are human identification methods commonly adopted in many information systems.One of their disadvantages is that an attacker who correctly observed an input password can impersonate the corresponding user freely.To overcome it there have been proposed interactive human identification schemes.Namely,a human prover who has a secret key is asked a question by a machine verifier,who then checks if an answer from the prover matches the question with respect to the key.The resistance of such a scheme can be evaluated by the probability P(n)of which an attacker can correctly answer a given question after observing n pairs of questions and correct answers.However no schemes have been sufficiently evaluated so far.This correspondence constructs a new interactive human identification scheme based on linear algebra and proves its resistance by showing a rigorous profile of P(n). |
