Today a large volume of data is stored in cloud that requires fine grained accessibility for heterogeneous users. Cipher-text policy attribute based encryption (CP-ABE) has evolved into promising solution secure storage with access control. In CP-ABE, the ciphertext associated an (set rules) and users can if their attributes satisfies policy. However, existing CP-ABE schemes fail to perform presence number hierarchical relationships among them. Moreover, majority require computational overhead light weight applications. this paper, we present cryptosystem by introducing dependency between thereby achieving multi-layer verification access. our proposed seamless user revocation. The efficiency security have been analyzed reported. Further implement Charm demonstrate its practicality.
