基于证书的同态聚合签名方案在智慧家居传感器网络中的应用

Application of Certificate Based Homomorphic Aggregation Signature Scheme in Smart Home Sensor Networks

随着人工智能、云计算、云存储和物联网技术的发展,智慧家居作为新兴产业,已逐步走进人们的视野。智慧家居系统是基于物联网技术构建的,系统边缘由大量无线传感器构成,因此保证各边缘传感器采集数据在云服务器端的完整性是一个重要的研究课题。基于证书的同态聚合签名方案可方便地部署在智慧家居系统之上,并能快速、高效地实现对智慧家居云端多用户数据完整性的批量验证。方案在安全方面可以抵抗基于证书同态签名中超级攻击者的攻击,同时能够防止聚合签名中来自恶意攻击者的合谋攻击。通过JPBC密码学库对方案性能进行仿真实验,结果表明,相比其他方案,该方案在签名验签时的计算开销更小,可大幅提升智慧家居系统中云端多用户数据完整性的批验证效率。

With the development of artificial intelligence,cloud computing,cloud storage,and the Internet of Things technology,smart home,as an emerging industry,has gradually entered people´s vision.The smart home system is built on top of the Internet of Things technolo⁃gy,and the system edges are composed of a large number of wireless sensors.Ensuring the integrity of data collected by each edge sensor on the cloud server is an important research topic.The certificate based homomorphic aggregation signature scheme can be easily deployed on smart home systems and can quickly and efficiently achieve batch verification of multi user data integrity in the smart home cloud.The scheme can resist attacks from super attackers in certificate based homomorphic signatures in terms of security,while also preventing collusion attacks from malicious attackers in aggregated signatures.After conducting simulation experiments on the performance of the scheme using the JPBC cryptographic library,the results show that compared to other schemes,this signature scheme has lower computational overhead during signa⁃ture verification,and can significantly improve the efficiency of cloud based multi user data integrity batch verification in smart home systems.
