ABSTRACT

Among the up-and-coming technologies, cloud computing provides an elastic, self-service computing infrastructure for a wide range of applications. It’s all about transforming resources from the single desktop computer/personal laptop/data centers to web. The user’s data can be placed, within the cloud storage and it can be accessed by the clients whenever they like and from anywhere they need. Here so many security problems can be raised. Managing and controlling identities and access control for a data with an authoritative or unauthorized way is still a greatest challenges in cloud security. In a cloud environment, the data proprietor and cloud service provider have ability to monitor the data access activities in order to prevent from unauthorized access. In this article, we give attention to a variety of access control echniques, their performance, properties and implementation for cloud environments.
