对于可搜索对称加密方案（或带关键字搜索的对称密钥加密方案），迄今为止主要考虑的是被动对手的安全性（即隐私）。在本文中，我们首先定义了它对主动对手的安全性（即可靠性和隐私性）。接下来我们制定UC-security。然后，我们证明了针对非自适应对手的uc安全性等同于我们对隐私和可靠性的定义。我们进一步提出了一个满足我们的安全定义（因此是UC-security）的有效构造。
For searchable symmetric encryption schemes (or symmetric-key encryption with keyword search), the security against passive adversaries (i.e. privacy) has been mainly considered so far. In this paper, we first define its security against active adversaries (i.e. reliability as well as privacy). We next formulate its UC-security. We then prove that the UC-security against non-adaptive adversaries is equivalent to our definition of privacy and reliability. We further present an efficient construction which satisfies our security definition (hence UC-security).
