Attribute based encryption in cloud computing

Abstract

Cloud acts as a database for huge amount of data. It allows users to store the information or data related items in the cloud storage and allows them to use/ their data via network connection. There are different types of cloud, Public private hybrid and community. In case of public cloud the user rents the storage and stores the data in it. There exist some trust issues in storing data in the cloud since there are many untrusted users who also rented the cloud and there is need for the encryption of data there are many ways to encrypt the data the new trend in encryption is attribute based encryption. The main advantage in attribute based encryption is that it depends on the attributes of the user which differs vastly from one user to another. This paper explains about the use of attribute based encryption in cloud and how it differs from the other encryption algorithms and it advantages over other algorithms. This paper also explains about the cipher-text policy in ABE in various aspects.
