摘要

Boneh等人提出的公钥加密关键字搜索(PEKS)模型使人们能够在不泄露数据任何信息的情况下搜索加密的关键字。Baek等人提出了一种增强模型，称为无安全通道PEKS (SCF-PEKS)，以消除昂贵的安全通道。然而，大多数现有的SCF-PEKS方案在随机oracle模型下被证明是安全的。2009年，Fang等人提出了一个没有随机神谕的SCF-PEKS方案。但该方案需要一个强大而复杂的假设。在本文中，我们提出了一个在标准模型中假设简单的SCF-PEKS方案。

A SCF-PEKS Scheme without Random Oracle under Simple Assumption

The model of public key encryption with keyword search (PEKS) proposed by Boneh et al. enables one to search encrypted keywords without revealing any information on the data. Baek et al. proposed an enhanced model called secure channel-free PEKS (SCF-PEKS) to removes the costly secure channel. However, most of the presented SCF-PEKS schemes were proved secure in the random oracle model. In 2009, Fang et al. presented a SCF-PEKS scheme without random oracles. But the scheme requires a strong and complicated assumption. In this paper, we propose a SCF-PEKS scheme that is under simple assumption in the standard model.
