Survey on cloud security using attribute based encryption
Soni Kumari, Dr. SB Sonkamble
Cloud computing has become more popular nowadays. It gives many advantages as it provides low cost and makes use of large share storage and processing resources. But with the growth of online system, the cost of storage infrastructure increases. Another concern is security. When storing and processing the data within the same cloud provided by multiple users, it causes effects on security and privacy. However, most of the work focus on the data content privacy and access control, whereas less focus on the privilege control and the identity privacy. So, this paper presents a semi anonymous privilege control and full anonymous privilege control as Anony Contol and Anony Control-F respectively. It ensures not only data privacy, but also prevents the identity leakage that is identity privacy. The second issue is when multiple users provide the data or share files in same cloud, the number of files increases, which leads to less storage space and the duplication of files increases. For this reason, to decrease the duplication of files and to increase security among users for file sharing use to combine data index technique with ABE (Attribute Based Encryption) system, which integrates data de-duplication for remove duplicate file in cloud storage and give storage optimization and provide security for multiple users for accessing the same data.
