One of
the effective way to ensure data security in cloud computing is data access
control. Due to untrusted and outsourcing cloud server, the control of data
access became a challenging issue in cloud computing. One of the most
suitable technology for data control in cloud Is Ciphertext-Policy
Attribute-based Encryption (CP-ABE) , because it gives control to the data
owners on direct access policies. It is somewhat difficult to apply existing
Ciphertext-Policy Attribute-based Encryption (CP-ABE) scheme to cloud data
access control because of the attribute revocation problem. In this paper, we
design an revocable, expressive and well-organized data access control for
multi authority cloud storage, where there are multiple authorities co exist
and each authority is able to issue attributes independently. We propose a
revocable multi-authority Ciphertext-Policy Attribute-based Encryption
scheme, and apply it is the principal techniques to design the data access
control scheme. Our revocation attribute method can efficiently achieve both
backward security and forward security. The analysis results show that our
proposed data access control scheme is secure in the casual oracle model and
is more efficient than previous works. Sampath Kumar Tatipally | Dr. K. Shahu
