摘要
基于可验证多秘密共享,提出一种新的共享验证数字签名方案。该方案有效地克服了已有的共享验证签名方案在安全方面的不足,在验证签名的过程中,验证组可以防止因某些成员提供假的信息而造成验证失败。该方案使用的可验证多秘密共享,能够通过一次秘密共享验证多个签名的有效性。与现有方案相比,效率有了一定提高。
This paper presents a signature with shared verification scheme based on verifiable multi-secret sharing. The scheme effecitively overcomes the deficiencies of the previous schemes in terrns of security. In the process of signature verification, validation group can prevent some members providing the faulted information. This can make verification failure. Because the scheme uses verifiable multi-secret sharing, it can verify many signatures when it makes once multi-secret sharing. It has higher efficiency compared with the previous schemes.
