Re-encryption based Attribute Revocation in Data Access Control for Multiauthority Cloud Storage

Kalyani G. Ktangale, Milind Penurkar

Abstract: In Services including private users, businesses and governments, Cloud computing technologies are gaining importance at a very higher level. Cloud computing provides transparency, but sharing of resources at a distributed level has severe implications when sensitive or privacy-relevant data is concerned. To ensure the data security in cloud Data access control is an effective way. But due to the untrusted cloud servers, data access control becomes a challenging issue in cloud storage systems. However after attribute revocation if we have to provide security through re-encryption, then this is not given.In this paper we proposed certificate less encryption-based schemes by relying on a public cloud server and we apply it as underlying techniques to design the data access control scheme. Our certificate less encryption method can efficiently provide both forward security and backward security.
