Suyel Namasudra, Pinki Roy, Balamurugan Balusamy · 2017
Nowadays, access control and data security are two most critical problems with cloud computing. Access control can be defined as a procedure by which users can access data from the cloud server. At the time of accessing data, there are many problems, such as data security, high data accessing time, data lost, overhead, data redundancy, etc. In the first part of this paper, a brief discussion of fundamentals of cloud computing are presented. Moreover, all the issues of cloud computing are also discussed in this paper. Finally, future work directions have been identified for the cloud computing environment.
