Research And Application Of Trusted Storage Technology For Network Community Data

Network community public opinion data are often the hot events of concern and data on views and comments on these events.By analyzing the data of network community,we can not only grasp the hot topics that the masses are concerned about,but also timely monitor sensitive information scattered in the network community,so as to create a good network community environment.Because of this,the storage and use of public opinion analysis data in the open network environment also exists the risk of information leakage,aiming at the problem of poor flexibility and low reliability existing in existing trusted storage models,it is also the key and difficult point for network community data to achieve credible and secure data storage and trusted authentication.By investigating the current popular trusted storage model at home and abroad,the TPM based hierarchical encapsulation storage mode is adopted.Therefore,trusted storage based on TPM as trusted root is used to store trusted data in network communities.Aiming at the problem of information change due to the update of TPM platform,we choose the reasonable PCR value of TPM platform and the generated random number to package it.In view of the complex and diverse data of the network community,a hierarchical storage scheme is designed to improve the storage efficiency.The network community has a large amount of data and a wide variety of data,using a distributed data storage framework to store the data trusted.On the basis of the trusted storage model,the trusted verification of network community data is realized by introducing the challenge response mechanism introducing TPM as the verifier.Finally,a trusted data storage model,which is more suitable for network community data storage,is finally realized.The experiment uses the Internet information data and the consumer's consumption data in the network community,compared with the benchmarking trusted storage model and trusted verification mechanism,the results are compared and analyzed.The experimental results show that the improved network community data trusted encapsulation storage model is guaranteed the trusted storage of network community data.Compared with the benchmarking trusted authentication mechanism,the optimized storage data trusted verification mechanism has improved the validation efficiency by 8%?9%.Thus it lays a technical foundation for realizing the trusted storage of network community data and effectively reducing the risk of disclosure of public opinion analysis data.
