Comparative study of attribute based encryption techniques in cloud computing
R. Manjusha, Rahul Ramachandran · 2014
Cloud computing is a model on which organization and individuals can work with application from anywhere in the world on demand. The major issue of cloud computing is preserving confidentiality and integrity of data in data security. The primary solution to this problem is encrypting cloud data. Security in cloud computing being one of the classic research topic. Many techniques have been proposed on attribute based encryption techniques. In this paper multi authority hierarchical attribute based encryption is proposed and it is compared with key policy and cipher text policy attribute based encryption techniques. Based on NIST statistical test highest security attribute based encryption algorithm is selected in cloud.
