基于环签名的食品质量安全匿名举报方案

Anonymous reporting scheme based on ring signature for the safety of food quality

以食品质量安全为研究对象,通过引入可验证环签名技术,提出了一种食品质量安全匿名举报方案.该方案在整个签名过程中巧妙地配置了举报者和政府监管部门的操作,举报者既可以隐藏自己的身份信息,又可以揭示自己的身份信息.政府监管部门只进行两次双线性对运算,极大地提高了网络的整体响应效率,有利于加快问题食品的监管效率.结果表明,该方案保证了举报者身份的隐私,保护了举报者的利益;同时,该方案也可以揭示举报者的身份,用于举报后的奖励机制.因此,该方案非常适用于构建安全、统一管理、协调、高效运作的食品安全监管系统中.

The safety of food quality was selected as the research object.An anonymous reporting scheme was proposed by employing the verifiable ring signature.The whistleblower and government regulators were properly configured with different workloads.Whistleblower could not only hide its identity informa-tion but also reveal it.This scheme only need two pairing computations for any group size in the govern-ment regulators in order to enhance the network efficiency.The results showed that the proposed scheme ensured the privacy of whistleblower and protected the interests of the whistleblower.At the same time, it could also reveal the identity of the whistleblower to reward.Therefore, it was concluded that the pro-posed scheme was well suitable for building the food safety regulatory system which had many great na-tures of the security, unified management, coordination and efficient operation.
