  4. Abstract:
  5. Strong Designated Verifier Signature (SDVS) provides authentication for the signer and the verifier such that the signer is assured that what s/he has signed, is only verified by the designated verifier. Currently, the security of most of the SDVS schemes is based on hard problems in the number theory. As it is proved that all kinds of cryptosystems which are based on the number theory will not tolerate quantum attacks, here, an SDVS scheme based on hard problems in coding theory is presented. We have proved that the suggested scheme is unforgeable under a chosen message attack in Random Oracle Model. Copyright © 2016 John Wiley & Sons, Ltd. Copyright © 2016 John Wiley & Sons, Ltd
