Hierarchical CP-ABE Scheme Implementation on Amazon EC2 Cloud

Cloud computing plays vital role in the development of IT industry. It can help a small organization to grow their business. An organization can move from small scale industry to large scale industry. Cloud refers internet based data, network, resource storage. So security, integrity, confidentiality requirement need must be fulfill by cloud implementation. Attribute based encryption with ciphertext policy provides efficient encryption of data. Hierarchical implementation implies that an organization can assign different privileges to users according to their role, using a top to bottom approach. Amazon Elastic Compute Cloud (EC2) has made web computing easier for developers. It connects to virtual resources according to user requirement of network resources. This paper describes the implementation of Hierarchical CP-ABE scheme on Amazon EC2 cloud. Also paper include efficiency of encryption and decryption scheme used in implementation.
