Abstract

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.

Highlights

In order to improve the inheritance and protection ability of ethnic sports, an association data mining model of ethnic sports inheritance and protection based on association rule feature extraction was proposed

Summary

Internet Node Secure Transmission Protocol Based on Trusted Computing

(1) Starting from the root of trustworthiness measurement, calculate the integrity measurement value of the system platform, establish the trust chain of the computer system platform, ensure the trustworthiness of the system platform, and resist malicious code attacks such as viruses [10]. (2) When the trusted identity of the sensor node is authenticated, the subenergy router generates and sends a random value nonce to the sensor node [14]. (4) At the same time, the sensor node uses the identity private key to encrypt the data, the random value nonce, PCR is calculated to obtain the signature Quote, and Quote, Updata is sent to the upper-level node. When node 101 gets s(n101) verification, add its own n101 to compare the hash value generated by the Merkle tree with the received h(n) If they are consistent, it indicates the validity of the source of the instruction. Discard the data packet [17]
