We present two fully secure functional encryption schemes: a fully secure attribute-based encryption (ABE) scheme and a fully secure (attribute-hiding) predicate encryption (PE) scheme for inner-product predicates. In both cases, previous constructions were only proven to be selectively secure. Both...

We elaborate Hierarchical Identity-Based Encryption (HIBE) with a new primitive referred to as Hierarchical Identity-Based Broadcast Encryption (HIBBE). Similar to HIBE, HIBBE organizes users in a tree-like structure and users can delegate their decrypti
Thus a privacy based security service in cloud is required. In this paper, we propose that security is achieved through domain based cloud service using hierarchical attributed based encryption scheme. The hierarchical attribute based security is provided by means of having a hierarchy like superior ...
