Updating Policy with Access Control Using Multi Authority in the Cloud

V. Kalpana | J. Daphney Joann

Abstract: The policy updating has always been a challenging issue when ABE is used to construct access control schemes and develop a new method to outsource the policy updating to the server. Attribute Based Access Control method is used to avoid the transmission of encrypted data and minimize the computation work of data owners, by making use of the previously encrypted data with old access policies. A policy updating algorithm called LSSS is used for efficient and secure method allows data owner to check whether the cloud server has updated the cipher texts correctly.
