基于区块链技术的物联网终端隐私数据聚合方法

Privacy Data Aggregation Method of Internet of Things Terminal Based on Blockchain Technology

为抵抗物联网内部与外部隐私数据泄露,修复并追查错误,提出一种基于区块链技术的物联网终端隐私数据的聚合方法。融合与压缩多媒体数据,减少数据占用容量,利用哈希函数非对称加密隐私数据,去除中心化数据使隐私数据区块化,依靠大素数设定公、私密钥并加以分配,依靠密钥估算整数签名,使用非退化可估算的双线映射验证整数签名拟定等式,若验证等式成立即聚合成功,反之则重新挑选整数签名进行验证,直至所有整数等式成立。实验证明,能够有效确保物联网终端隐私数据的安全,在追查数据泄露时会将传感器损失降至最低。

In order to resist the leakage of internal and external privacy data of the Internet of things,repair and trace errors,a method of aggregation of privacy data of Internet of things terminal based on blockchain technology is proposed.It fuses and compresses multimedia data to reduce data capacity.It uses hash function to encrypt private data asymmetrically,removes centralized data and makes private data block.Public and private keys are set and distributed by large prime number.Integer signature is estimated by key.Integer signature is verified by non regressive and estimable two line mapping.If the verification equation is proved,it is aggregated On the contrary,the integer signature is re selected for verification until all integer identities are established.Experiments show that it can effectively ensure the security of Internet of things terminal privacy data,and the sensor loss minimize when tracking data leakage.
