ABSTRACT = {Attribute-based encryption is cryptographic techniques that provide 
flexible data access control to encrypted data content in cloud storage. Each trusted 
authority needs proper management and distribution of secret keys to the user’s to 
only authorized user’s attributes. However existing schemes cannot be applied 
multiple authority that supports only a single keywords search compare to multi 
keywords search high computational burden or inefficient attribute’s revocation. In 
this paper, a ciphertext policy attribute-based encryption (CP-ABE) scheme has 
been proposed which focuses on multi-keyword search and attribute revocation by 
new policy updating feathers under multiple authorities and central authority. The 
data owner encrypts the keywords index under the initial access policy. Moreover, 
this paper addresses further issues such as data access, search policy, and 
confidentiality against unauthorized users. Finally, we provide the correctness 
analysis, performance analysis and security proof for chosen keywords attack and 
search trapdoor in general group model using DBDH and DLIN assumption.},
