Attribute Based Encryption (ABE) schemes is a vision of public key encryption mechanism that allows users to encrypt and decrypt messages based on user attributes. ABE takes attributes as public key and associates them with the ciphertext and user’s secret key. It is an efficient way to solve open problems in access control scenarios. In this paper, we survey the basic Attribute Based Encryption (ABE) scheme and its two varients: Keypolicy ABE (KP-ABE) scheme and the Ciphertext-policy ABE (CP-ABE) scheme.

The notion of database outsourcing enables the data owner to delegate the database management to a cloud service provider (CSP) that provides various database services to different users. Recently, plenty of research work has been done on the primitive of outsourced database. However, it seems that no existing solutions can perfectly secure a generic database and support the property of correctness of the results, especially in the case when the dishonest CSP intentionally returns an empty result to the user. Here presents an effective encrypted outsourced generic database which ensures the confidentiality of the sensitive data and the correctness of the search result even if the dishonest CSP returns empty result. For making the sensitive data more secure that is stored in the outsourced generic database, a framework is introduced which implement the concept of negative database on generic database(EAV mode...
