Efficient and Flexible Access Control for Outsourced Data In Cloud
Journal Title: International Journal of Research in Computer and Communication Technology - Year 2013, Vol 2, Issue 12
Abstract
This paper presents a scheme achieves scalability and also inherits flexibility and finegrained access control in supporting compound attributes of ASBE . In the other hand HASBE implement multiple value assignments for access expiration time to deal with user revocation more efficiently than existing schemes. Later we prove the security of HASBE based on the cipher textpolicy attribute-based encryption (CP-ABE) scheme by Bethencourt et al. and analyze its performance and computational complexity. We implement our scheme and show that it is both efficient and flexible in dealing with access control for outsourced data in cloud computing with comprehensive experiments.
