In this article, we first propose a continuous auxiliary inputs leakage model for the hierarchical attribute-based encryption scheme. Under the security model, an adversary has ability to gain partial updated m
forward securityCloud storage greatly facilitates both individuals and organizations to share data over the Internet. However, there are several security issues that impede to outsource their data. Among various approaches introduced to overcome these issues, attribute-based encryption (ABE) provides ...

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...

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 ...
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
