    Access control model for multi-source heterogeneous data in big data environment by Qiuyue SU, Xingshu CHEN, Yonggang LUO

    Published 2019-02-01
    “…The big data platform is open and shared,but with the increasing amount of data and the complex and variable user access context,the RBAC model is difficult to meet the fine-grained and flexible access control in big data environment.To solve this problem,an access control model for multi-source heterogeneous data in big data platform is proposed.The model dynamically determines role permissions based on attributes and builds a hierarchical structure based on data groups to achieve simple management of data attributes.The model is formally defined,and the implementation and workflow in Hadoop platform are described.The experimental results show that the performance overhead of the proposed scheme is relatively small.…”

    Multi-replica provable data possession scheme supporting data dynamic updating by Long CHEN, Yu-zhu LUO

    Published 2014-11-01
    “…Considering the application demand of multiple replicas data security and data dynamic update,a multi-replica provable data possession scheme was proposed to supporting data dynamic updating.The original data file can be dynamically updated using dynamic verification structure.The other multiple-replica data files are just append with a log-record for each dynamic update operation.The multi-replica files support public auditability and batch verification.If the original data or any replica is corrupted or missing,it can be recovered to the latest status with another copy.The performances of the communication and storage as well as the security are analyzed.The results show that the scheme is efficient and secure.…”
