A Novel Approach for Securing Data using Cipher Text Policy Attribute Based Encryption
With the recent assumption and diffusion of data sharing paradigm in distributed systems such as cloud computing or online social networks, there have been increasing concerns and demands for distributed data security. The support of policies updates and enforcement of access policies is one of the most challenging issues in data sharing systems. Cipher-text Policy Attribute-Based Encryption i.e. CP-ABE is becoming a challenging cryptographic solution to this issue has been enables for the data owners and to define their own data access policies over the user attributes and impose the policies on the data to be distributed.
