应用于物联网的Paillier同态信息检索方案设计

摘要

With the development of the internet of things, more and more encrypted data information stored on the cloud server. When the server stored encrypted data for a certain scale, the encrypted data retrieval become a urgent problem to be solve& The paper presents an information retrieval scheme based on Paillier homomorphic encryption algorithm, which is used in the Internet of things This algorithm can not only directly retrieve the encrypted data and ensure the retrieval of data not to be statistical analysis, but also can be retrieved the data in basic additive operation without changing the order of the plaintext. The data security of users is protected and the retrieval efficiency is improvel.%随着物联网的发展，越来越多的加密数据信息存储在云端服务器上，当服务端存储的加密数据形成一定规模后，对加密数据的检索成为一个迫切需要解决的问题。本文设计一种基于Paillier同态加密算法应用在物联网的信息检索方案。该算法可以直接对加密的数据进行检索，不但能保证被检索的数据不被统计分析，还能对被检索的数据做基本的加法运算而不改变对应明文的顺序，既保护了用户的数据安全，又提高了检索效率。
