(Convertible) undeniable signatures without random oracles

Journal Article


Abstract


  • We propose a convertible undeniable signature scheme without

    random oracles. Our construction is based on Waters and Kurosawa

    and Hengs schemes that were proposed in Eurocrypt 2005. The security

    of our scheme is based on the CDH and the decision linear assumption.

    Comparing only the part of undeniable signatures, our scheme uses more

    standard assumptions than the existing undeniable signatures without

    random oracles due to Laguillamie and Vergnaud.
