    Title: An Extendable-Message-Passing Protocol with Signature Based on Two Hard Problems and Its Applications

    Abstract: Recently, an improved digital signature scheme was
    proposed by He. However, there is a weakness in He’s
    scheme, where the forgers can forge valid signatures.
    In this paper, we show that there is also a drawback
    that a public key may have more than one
    corresponding secret key, where the verifier cannot
    determine who the real signer is. As a result, we
    improve He’s scheme to overcoming the above flaws.
    Moreover, we propose a message-passing protocol. In
    the proposed protocol, the delivered message can be
    extended by the valid senders, and the appended
    signatures are used to ensure the integrity of the
    message and to verify each signer of each sub-message.
