当用户和企业考虑部署云计算服务时,云安全是一个巨大的问题。本文主要介绍了云安全的一个重要方面,即可搜索加密。可搜索加密是一种使用户能够对存储在云中的加密数据进行安全搜索的方案。为了保证用户数据的隐私性,用户在上传之前对自己的数据文件进行加密,当用户需要获取某些文件时,可以使用可搜索加密对加密后的数据进行关键字搜索。可搜索加密可分为三种模型,每种模型对应不同的应用场景。其中两个适用于云架构。它们分别被称为可搜索公钥加密和可搜索对称加密。可搜索公钥加密主要用于数据共享场景。用户希望与其他用户私下共享一些数据文件。他可以用接收方的公钥加密这些文件。接收方可以用他们的私钥安全地搜索它。可搜索的对称加密可以使用户安全地使用他们的在线存储。他们可以上传用他们的密钥加密的数据文件。然后他们可以安全地搜索这些加密的数据,无论何时何地。
Cloud security is a huge concern when users and enterprises consider to deploy cloud computing services. This article mainly presented an important aspect of cloud security which is called searchable encryption. Searchable encryption is a scheme that enable users to secure search on encrypted data stored in cloud. To guarantee privacy of users’ data, users encrypt their data files before uploading, then when they need to fetch some files, they can use searchable encryption to execute keyword search on encrypted data. Searchable encryption can be classified by three models, each is corresponding with different application scenario. Two of them are suitable with cloud architecture. They are called searchable public key encryption and searchable symmetric encryption respectively. Searchable public key encryption is mainly for data sharing scenario. A user wants to share some data files with other users privately. He can encrypt these files with receivers’ public key. And receivers can securely search on it with their private keys. Searchable symmetric encryption can enable users securely using their online storage. They can upload data files which are encrypted with their secret keys. And then they can securely search on these encrypted data with the secret key no matter when and where they are.
