HASBE for Access Control by Separate Encryption/Decryption in Cloud Computing
Cloud computing has emerged as one of the most influential paradigms in the IT industry. In such area the data confidentiality, flexibility and access control are to be considered in the research area. Data owners and service providers are not in the same trusted domain in cloud computing. Enterprises usually store data in internal storage and install firewalls to protect against intruders. The data will be stored in storage provided by service providers. Service providers should not be a trusted one anyhow they are all third party. Propose a novel technique to Hierarchical Attribute Set Based Encryption (HASBE), it is driven by the Cipher Policy Attribute-Based Encryption (CP-ABE) with a hierarchical structure of cloud users.
