Summary:Cloud computing have brought a lot of advantages, such as reducing the hardware cost and providing a convenient cloud storage service. More and more people choose to put their private data in the cloud. To improve data security and privacy, Wu et al. proposed a new extensive data access control scheme for multi-authority cloud storage systems (NEDAC-MACS) on the basis of the scheme of Yang et al. In this paper, we propose a new scheme that can resist the collusion of the cloud server and user to improve the security of NEDAC-MACS. The cryptographic analysis show that our scheme is still secure in the random oracle.
