Aiming at the problems of low protection accuracy and long time consumption in traditional privacy data protection methods, a privacy data protection method based on trusted computing and blockchain is proposed. Set up the Internet node secure transmission protocol through the trusted node uplink transmission protocol and the downlink transmission protocol, and according to the transmission protocol, combined with the blockchain technology, the ECC elliptic curve encryption algorithm is used to encrypt the amount of data existing in the blockchain, and the AES symmetric encryption algorithm is used to encrypt the private data that exists in the nonblockchain, thereby completing the protection of network private data. The simulation experiment results show that the privacy data protection accuracy of the proposed method is higher and the work efficiency is faster.

基于可信计算和区块链的隐私数据保护研究

针对传统隐私数据保护方法保护精度低、耗时长的问题，提出了一种基于可信计算和区块链的隐私数据保护方法。通过可信节点上行传输协议和下行传输协议建立互联网节点安全传输协议，并根据传输协议，结合区块链技术，采用ECC椭圆曲线加密算法对存在于网络中的数据量进行加密。区块链，利用AES对称加密算法对存在于非区块链中的私有数据进行加密，从而完成对网络私有数据的保护。
