摘　　要：随着云存储技术的发展,越来越多的企业及个人将加密后的私有数据外包给云服务器,因此,对云服务器中加密数据的有效检索成为用户在选择云服务时关注的重点。通过分析国内外可搜索加密机制的研究成果,归纳了最新的可搜索加密技术,对现有的研究方法进行分类,包括支持关键字的可搜索加密机制、面向不同加密方式的可搜索加密机制和其他类的可搜索加密机制。分别分析总结了现有的不同的改进方法及其优缺点,特别研究分析了各类中最新的研究进展。对可搜索加密机制现阶段研究仍存在的信息泄露、实用性差以及搜索效率较低等问题进行了总结,并阐明了其未来可研究的方向。With the development of cloud storage technology,there is an increasing number of companies and individuals outsourcing their data to cloud sever, As a result,efficient retrieval of encrypted data stored on cloud server has become the issue that users may pay atten- tion to when selecting cloud services. The latest searchable encryption technologies are summarized by analysis of the research achieve- ment of searchable encryption technologies at home and broad,and the existing study methods are divided into different categories such as searchable encryption mechanism of supporting key words and of facing various encryption and others. The improved methods and their advantage and disadvantage are analyzed, especially for the latest development in each category. Some existing problems including infor- mation leakage, poor practicability and low search efficiency are summarized and further studies in the future are pointed out.
