Abstract: Cloud computing is very emerging area in IT industries.
In a cloud environment, many distributed systems are interconnected to
provide software, hardware and resources over the internet. Since this new
paradigm requires users to ensure the security of their personal data, there
are gradually increasing security and privacy issues on outsourced data. A
natural way to keep the data in a confidential manner is to encrypt it
before storing on cloud server. The main problems of this process include
building scalable access control for storing data and revoking access rights
from users if they are revoked from the system. Many access control schemes
have been already developed. In this paper, a taxonomy and brief survey of
secure data access control schemes in cloud environment have been presented.
The current research issues and future work directions are also presented in
this paper in the area of security of cloud computing.
