Embodiment 1

[0022] Such as figure 1 As shown, a design of a trusted distributed file system based on HDFS includes a remote certification module and a data sealing module, and the remote certification module includes: a remote certification module based on the integrity measurement framework IMA, which is used for the applicant to establish a connection The activation certificate provides the applicant with a valid TPM certificate; the remote procedure call remote certification module is used to perform remote certification when establishing a remote procedure call connection between HDFS entity nodes to ensure the platform status of the remote procedure call initiator Integrity; the socket connection remote certification module is used for remote certification when the entity node connects to an untrusted address to avoid platform data leakage. The data sealing module is used to seal the data after the remote certification fails, seal the stacked key through the PCR value, and encrypt th...

Abstract

The invention discloses a credibility distribution type file system based on an HDFS. The credibility distribution type file system comprises a remote attestation module and a data sealing module. The remote attestation module comprises a remote attestation module body based on an integrity measurement architecture IMA, a remote procedure call remote attestation module and a socket connection remote attestation module. The data sealing module comprises a module for conducting data sealing after remote attestation fails. The credibility distribution type file system based on the HDFS has the advantages that a credibility safety mechanism is added in an HDFS distribution type file system, so that the creditability of interaction objects is determined when data interaction is conducted between entity nodes, non-credible addresses of system connection can be blocked after the system integrity is damaged, and data are sealed after remote attestation failure to ensure that the data are not leaked.

Description

technical field [0001] The invention relates to the field of trusted computing, in particular to a trusted distributed file system based on HDFS. Background technique [0002] Due to the rapid development and widespread popularization of information technology in recent years, a large amount of data has grown exponentially, and large companies such as Google, Yahoo, and Amazon are facing the challenge of massive data. Google took the lead in launching the Google file system GFS and MapReduce to deal with the storage and processing of massive data, which attracted widespread attention and quickly gave birth to an open source version called Hadoop. After rapid development in recent years, Hadoop has become an important part of the basic computing platform of Internet companies. It has its own customized versions in domestic large enterprises such as Tencent, Baidu, and Alibaba, as well as large foreign enterprises such as Twitter and Facebook. . Hadoop is specially designed ...
