Data Block Management Scheme Based on Secret Sharing for HDFS

In the cloud computing environment, data are encrypted to be stored in many distributed servers. Global Internet service providers such as Google and Yahoo recognized the importance of an Internet service platform and have used low-priced commercial-node-based and large-scale cluster-based cloud computing platform technologies through R&D. As various data services have been available in the distributed computing environment, the distributed management of big data has become a major issue. In the various uses of big data, security vulnerability and privacy invasion may occur due to malicious attackers or inner users. In particular, various types of security vulnerability occur in the block access token, which is used for the permission control of the data block in Hadoop. To supplement the security vulnerability, a secret-sharing-based block access token management technique is suggested in this paper.
