“…This solution utilized the logical formalism provided to implement advanced rule management, such as semantic conflict detection. According to combination RBAC with ciphertext policy attributes, [171] proposed a RBAC-CP-ABE scheme of data protection mechanism. Security analysis showed that this scheme maintained the security and efficiency characteristics of the CP-ABE scheme, but greatly improved the access control capability.…”

Privacy and security are the most important issues to the popularity of cloud computing service. In recent years, there are many research schemes of cloud computing privacy protection based on access control, attribute-based encryption (ABE), trust and reputation, but they are scattered and lack unified logic. In this paper, we systematically review and analyze relevant research achievements. First, we discuss the architecture, concepts and several shortcomings of cloud computing, and propose a framework of privacy protection; second, we discuss and analyze basic ABE, KP-ABE (key policy attribute-based encryption), CP-ABE (ciphertext policy attribute-based encryption), access structure, revocation mechanism, multiauthority, fine-grained, trace mechanism, proxy re-encryption(PRE), hierarchical encryption, searchable encryption(SE), trust, reputation, extension of tradition access control and hierarchical key; third, we propose the research challenge and future direction of the privacy protection in the cloud computing; finally, we point out corresponding privacy protection laws to make up for the technical deficiencies. INDEX TERMS Cloud computing, privacy, access control, attribute-based encryption, trust.

The current trend of research in cloud computing is challenging and keenly marginal to understand for the researchers and the learners due to its over-cover and complementary nature towards the new technologies. Cloud Computing is part and parcel of its applications with a majority of the extending concepts of Fog Computing, Internet of Things (IoT) and Big Data Analytics. In the current scenario, it is difficult for a researcher to identify the domain applicability and interrelationship among all the specified areas. In view of this, the current study is planned to focus on the research requirements and the basics for majorly two categories of stakeholders -the learners and the researchers exploring the needs of users to cater by cloud and also the current research trends in cloud computing.

“…A key characteristic of RBAC is that it allows the specification and enforcement of various constraint policies [21][22][23], such as cardinality constraints and separation-of-duty constraints (also called separation-of-duty policies), which can reflect security policies of different enterprises and organizations and ensure system security. The cardinality constraint limits the maximum number of roles related to users or to permissions, the maximum number of permissions a role can have, or the maximum number of users to which a role can be assigned [14].…”

Role-Mining Optimization with Separation-of-Duty Constraints and Security Detections for Authorizations

Role-based access control (RBAC), which has been regarded as one of the most popular access-control mechanisms, is featured by the separation-of-duty constraints, mutually exclusive constraints, and the least-privileges principle. Role mining, a bottom-up role-engineering technology, is an effective method to migrate from a non-RBAC system to an RBAC system. However, conventional role-mining approaches not only do not consider the separation of duty constraints, but also cannot ensure the security of a constructed RBAC system when the corresponding mined results violate the separation of a duty constraint and/or the least-privileges principle. To solve these problems, this paper proposes a novel method called role-mining optimization with separation-of-duty constraints and security detections for authorizations (RMO_SODSDA), which mainly includes two aspects. First, we present a role-mining-optimization approach for satisfying the separation of duty constraints, and we constructed different variants of mutually exclusive constraints to correctly implement the given separation of duty constraints based on unconstrained role mining. Second, to ensure the security of the constructed system and evaluate authorization performance, we reduced the authorization-query problem to a maximal-satisfiability problem. The experiments validate the effectiveness and efficiency of the proposed method.
