【摘要】：随着大数据与云计算的发展,以可搜索加密为核心技术的安全搜索问题日益成为国内外研究的热点.围绕可搜索加密的新理论、新方法和新技术,针对可搜索加密的模式、安全性、表达能力和搜索效率等方面进行综述.主要内容如下:安全搜索必不可少的新理论研究进展,包括可搜索加密、属性基加密及其轻量化等相关理论问题的研究情况介绍;基于公钥密码算法(包括轻量化公钥密码算法)的安全搜索研究中,提出的减少公钥密码算法的使用次数的新方法概述;针对体域网、车载网、智能电网等新兴网络应用服务,介绍了前述新理论、新方法的应用情况.实现安全搜索,通常将不得不多次使用开销极大的公钥密码算法,所以在资源受限的网络中"怎么使用公钥密码算法"就成为一个关键问题.因此除了轻量化实现技术,减少使用公钥密码算法的次数(尤其是只使用一次)应成为高效解决这类问题的最为关键的步骤.此外,还指出了该领域当前研究中需要解决的公开问题和未来的发展趋势.
[Abstract]:With the development of big data and cloud computing, the security search problem with searchable encryption as the core technology has become a hot research topic at home and abroad. Around the new theory, new method and new technology of searchable encryption, aiming at the searchable encryption mode, The main contents are as follows: the research progress of the new theory of security search, including searchable encryption, This paper introduces the research of attribute based encryption and its lightweight, and the research of security search based on public key cryptography (including lightweight public key cryptography). A new method to reduce the number of use of public key cryptography algorithm is proposed, and the application of the new theory and method mentioned above is introduced for new network application services such as body area network, vehicle network, smart grid and so on. Public key cryptography algorithms often have to be used many times, so "how to use public key cryptography" in resource-constrained networks becomes a key issue. Reducing the frequency of using public key cryptography algorithm (especially only once) should be the most important step to solve this kind of problem efficiently. In addition, the open problems and the future development trend in this field are pointed out.
