HDFS-oriented cryptographic key resource control mechanism
Published 2022-09-01“…The big data environment presents the characteristics of multi-user cross-network cross-access, multi-service collaborative computing, cross-service data flow, and complex management of massive files.The existing access control models and mechanisms are not fully applicable for big data scenarios.In response to the needs of fine-grained access control and multi-service strategy normalization for cryptographic data in the big data environment, starting from the scene elements and attributes of access control, the HDFS-oriented CKCM was proposed by mapping the cyberspace-oriented access control (CoAC) model.Subsequently, a fine-grained access control management model for HDFS was proposed, including management sub-models and management supporting models.The Z-notation was used to formally describe the management functions and management methods in the management model.Finally, the CKCM system was implemented based on XACML to realize fine-grained secure access control for managing file and secret keys in HDFS.…”

Three-Point Boundary Value Problems for the Langevin Equation with the Hilfer Fractional Derivative
Published 2020-01-01“…We discuss the existence and uniqueness of solutions for the Langevin fractional differential equation and its inclusion counterpart involving the Hilfer fractional derivatives, supplemented with three-point boundary conditions by means of standard tools of the fixed-point theorems for single and multivalued functions. We make use of Banach’s fixed-point theorem to obtain the uniqueness result, while the nonlinear alternative of the Leray-Schauder type and Krasnoselskii’s fixed-point theorem are applied to obtain the existence results for the single-valued problem. …”
