TSHC: Trusted Scheme for Hadoop Cluster

Hadoop is a Apache project, which has be used at many fields, such online media companies including Facebook, Yahoo, educational service, government. However, there are some security risks or untrust risks in the Hadoop cluster. In the paper, a Trusted Scheme for Hadoop cluster (TSHC) to protect data security with Trusted Computing and cryptography technology is proposed. We first propose the trusted architecture framework for Hadoop cluster with Trusted Computing Base. And then some protocols, which are key management, node trusted management protocol, client access management protocol, node access management protocol, job executing management and data storage and update management, are developed. Moreover, the security analysis proves that the TSHC can efficiently meet the security requirement of Hadoop.
