“…We specifically chose the Key-Policy Hierarchical Attribute-Based (KP-HABE) variant, since its characteristics align well with the demands of our envisioned system.In particular, our system stores EHRs in hierarchical structures and demands to control access levels according to users' privilege scope. HABE is a generalization of the Hierarchical Identity-based Encryption (HIBE) scheme [22,57] and can be classified into two categories of Key-Policy HABE (KP-HABE) [26] and Ciphertext-Policy HABE (CP-HABE) [25].…”

Data and analytics are indispensable parts of any successful business. Despite that, they can lead to serious privacy issues if not used safely. Even though the financial and legal consequences of privacy breaches are profound, the most damaging one, in the long run, is customer distrust. This is particularly the case for hypersensitive data such as personal health information. In recent years, the significance of privacy, security, and trust to the design of successful modern systems are being recognized more than ever before. Nevertheless, the current state of data management systems is far from achieving this goal. Particularly, in medical data management systems, handling sensitive data, mistrust is a barrier to many core processes such as data collection, sharing and analytics. Consequently, it is a primary cause of suboptimal medical services in our time. The primary direction of this thesis is to respond to these concerns of ethical nature by taking data privacy as a fundamental human right into serious consideration in the design of these processes. We highlight the emerging role of the blockchain in health information systems and recognize blockchain's ample opportunities for trust establishment. Consequently, we propose solutions based on this novel technology. More precisely, this thesis proposes a privacy-preserving data market for incentivedriven data collection for the development of reliable mathematical models that accelerate medical research. The blockchain aspect of the platform provides transparency as to the purpose for which the data is used to avoid the perception of data misuse/abuse. Secondly, this thesis proposes flexible blockchain-based access control mechanisms with multiple privacy protection layers for user-centric data sharing. Furthermore, it proposes a distributed machine learning-as-a-service platform for data analytics whose computational integrity can be verified efficiently by users. The strength of this platform lies in mutual privacy protection of user data and service provider intellectual property.

<p style='text-indent:20px;'>Functional Encryption (FE) expands traditional public-key encryption in two different ways: it supports fine-grained access control and allows learning a function of the encrypted data. In this paper, we review all FE classes, describing their functionalities and main characteristics. In particular, we mention several schemes for each class, providing their security assumptions and comparing their properties. To our knowledge, this is the first survey that encompasses the entire FE family.</p>

“…In practical applications of cloud computing service, hierarchical management mode is usually used for such applications, such as hierarchical identity-based encryption (HIBE), hierarchical attribute-based encryption (HABE, Fig. 13) and hierarchical attribute-set-based encryption (HASBE) and so on [72].…”

“…HIBE improves the scalability of IBE by sharing the workload of root private key generator (PKG) among several lower-level pkg, thus facilitating the private key delegation. Because of its structure, HIBE can be deployed in cloud computing, pervasive computing systems, wireless sensor networks to provide access control [72]. At present, almost all existing HIBE schemes have a disadvantage that ciphertext size or private key size must depend on the hierarchical depth of identity.…”

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.
