在公钥加密中，我们可能希望让某人能够测试某个东西是否是给定文档中的关键字，而不会泄露文档的任何其他信息。例如，可能期望电子邮件网关测试电子邮件是否包含关键字“紧急”，使得它可以相应地路由电子邮件，而不将任何内容泄漏到网关。这种机制被称为关键字搜索公钥加密[4]。类似地，用户可能想要使电子邮件网关能够结合地搜索关键词，诸如来自“Bob”的关于“财务”的“紧急”电子邮件，而不泄露关于该电子邮件的任何其他内容。我们称这种机制为带有合取字段关键字搜索的公钥加密。在本文中，我们定义了该机制的安全模型，并提出了两个有效的方案，其安全性证明在随机预言模型。
In a public key encryption, we may want to enable someone to test whether something is a keyword in a given document without leaking anything else about the document. An email gateway, for example, may be desired to test whether the email contains a keyword “urgent” so that it could route the email accordingly, without leaking any content to the gateway. This mechanism was referred aspublic key encryption with keyword search[4]. Similarly, a user may want to enable an email gateway to search keywordsconjunctively, such as “urgent” email from “Bob” about “finance”, without leaking anything else about the email. We refer to this mechanism aspublic key encryption with conjunctive field keyword search. In this paper, we define the security model of this mechanism and propose two efficient schemes whose security is proved in the random oracle model.
