摘要

近年来区块链技术取得广泛关注，涌现出众多基于区块链技术的新型应用，其中以 StorJ、Filecoin为代表的去中心化存储应用取得了较好的市场反响。对比传统中心化存储，去中心化存储为用户提供了全新的数据存储思路，令用户在获得更好的服务伸缩性的同时，有效降低数据存储的成本。但在现有的去中心化存储方案中，用户的隐私不能得到有效保护。基于此，介绍了一种利用加密搜索技术对去中心化存储方案进行加强的方法。新方法将动态累加器算法引入加密搜索过程中，保障用户存储内容隐私并提供了更好的加密搜索性能。

Abstract

Since the flourish of the blockchain technology

a series of applications based on blockchain technology are emerging

and the decentralized storage service becomes the killer App in the decentralized markets

such as StorJ

Filecoin.Comparing with the centralized storage

decentralized storage are more secure

cheaper and more scalable.However

client’s privacy cannot be protected in existed decentralized storage apps.The idea of implementing the searchable encryption scheme with decentralized storage was proposed to improve the user’s privacy and utilizing the dynamic accumulator to improve the search efficiency of the searchable encryption scheme.
