Abstract — The emerging cloud technologies, due to their various unique and attractive properties, are rapidly being adopted throughout the IT industry. In this paper, we identify security challenges that arise in incorporation of cloud-based services, and present a set of solutions to address them. To assure the user control over the access to their own data, it is a promising method to encrypt the data before outsourcing on cloud. Main issues such as privacy, scalability in key management, flexible access and efficient user revocation which are the most important considerations for gaining finegrained, cryptographically used data access control.
