IMPLEMENTATION OF DATA CONFIDENTIALITY USING IMPROVED KP-ABE SYSTEM

In cloud computing there is problem associated with whole life of cloud data. For storage three important aspects of data is Data confidentiality, Data integrity and availability. Data encryption is used for confidentiality. Now, after this encryption data is sent to storage. Now, after the user supplies its key than the data is opened. Thus to provide user based security control for cloud provider is the primary objective of this work and can be achieved by Holomorphic encryption. Key management is another problem because the user is not expert to manage keys. The user has faced such problems. To develop a security architecture and implement client based confidentiality tool for storage in cloud computing and evaluate traditional security solutions and identify their remaining issues by which overall performance gets degraded. We will implement homomorphic encryption using improved KPABE system to achieve data confidentiality
