Lightweight Attribute Based Data Access Control and Advanced Access Structures for Clouds

Abstract

Cloud storage has the notorious security pitfalls of untrusted server, newlineoutsourcing of storage and decryption and other tasks. In view of these security challenges, newlinecloud data sharing depicts the major data access control issues of tampering, leakage, newlineunauthorised disclosure and other malicious attacks. Access control is the domain of newlineinformation security which achieves the detailed data access restrictions. Attribute Based newlineAccess Control (ABAC) is identified to be the advanced access control for implementing newlinefine-grained authorization and hence privacy-preserving data communication in cloud newlinesystems newline
