On The Security of Data Access Control for Multi-Authority Cloud Storage Systems

Abstract

Data access control has turning into a testing issue in cloud storage systems. A few methods have been proposed to accomplish the protected data access control in a semi confided in cloud storage system. As of late, K.Yang et al. proposed a fundamental data access control scheme for multiauthority cloud storage system (DAC-MACS) and an extensive data access control scheme (EDAC-MACS).
