The data privacy concerns are increasingly affecting the Internet of things (IoT) and artificial intelligence (AI) applications, in which it is very challenging to protect the privacy of the underlying data. In recent, the advancements in the performances of homomorphic encryption (HE) make it possible to help protect sensitive and personal data in IoT applications using homomorphic encryption based schemes. This paper proposed a practical homomorphic encryption scheme that can enable data users in IoT systems to securely operate data over encrypted data, which can effectively protect the privacy of key data in the system. The experimental results demonstrated the effectiveness proposed scheme.

数据隐私问题越来越多地影响到物联网（IoT）和人工智能（AI）应用程序，在这些应用程序中，保护基础数据的隐私性非常具有挑战性。最近，同态加密（HE）性能的进步使得可以使用基于同态加密的方案来帮助保护IoT应用中的敏感和个人数据。本文提出了一种实用的同态加密方案，该方案可以使物联网系统中的数据用户通过加密数据安全地操作数据，从而可以有效地保护系统中关键数据的私密性。实验结果证明了该方案的有效性。
