Implementation of MA-ABE for Better Data Security in Cloud

The more sensitive data is shared and stored by the third party references on the Internet, the need of encrypting data stored at these sites. The one drawback of encrypting data, is that it can be selectively shared at a coarse-grained level (i.e.; issuing another party the authors' private key), Here, they develop a new cryptosystem concept for fine grained sharing of encrypted data that they call multi authority attribute based encryption MA-ABE. The scheme proposed allows any polynomial number of independent authorities to monitor attributes and distribute secret keys.
