Improving Security and Efficiency in Attribute-Based Data Sharing

M. Pratheepa, R. Bharathi

Abstract: The key generation center could decrypt any messages addressed to specific users by generating their private keys. This is not suitable for data sharing scenarios where the data owner would like to make their private data only accessible to designated users key. so overcome this problem we propose escrow problem which means a written agreement delivered to a third party and Attribute-based encryption (ABE) is a promising Cryptographic approach fine-grained data access control which is provides a way of defining access policies based on different attributes of the requester, environment, or the data object. The KGC can decrypt every cipher text addressed to specific users by generating their attribute keys. This could be a potential threat to the data confidentiality or privacy in the data sharing systems.

Keywords: Data sharing, attribute-based encryption, revocation, access control, removing escrow
