“…Moreover, the scheme support policy update when patient wants to change the access policy associated with ciphertext, but simple access structures can be implemented. Xia et al [14] proposed attribute-based access control scheme with efficient revocation in cloud computing. It could support an efficient user revocation mechanism, but it can't protect the user's attribute privacy.…”

As a new kind of patient-centred health-records model, the personal health record (PHR) system can support the patient in sharing his/her health information online. Attribute-Based Encryption (ABE), as a new public key cryptosystem that guarantees fine-grained access control of outsourced encrypted data, has been used to design the PHR system. Considering that privacy preservation and policy updating are the key problems in PHR, a privacy-preserving multiauthority attribute-based encryption scheme with dynamic policy updating in PHR was proposed. In the scheme, each of the patient's attributes is divided into two parts: attribute name and attribute value. The values of the user's attributes will be hidden to prevent them from being revealed to any third parties. In addition, the Linear Secret-Sharing Scheme (LSSS) access structure and policy-updating algorithms are designed to support all types of policy updating (based on "and", "or", and "not" operations). Finally, the scheme is demonstrated to be secure against chosen-plaintext attack under the standard model. Compared to the existing related schemes, the sizes of the user's secret key and ciphertext are reduced, and the lower computing cost makes it more effective in the PHR system.

“…Additionally, the authors introduced an efficient revocation scheme to supports both backward and forward security. In Xue et al [16] explored an approach of cloud side access control mechanism for encrypted data storage. From the proposed scheme can secure the cloud storage from the external attacks and offers power consumption accountability.…”

The recent technological advancement has taken cloud computing (CC) infrastructure to a significant level where the increasing level of research interest laid upon cost-effective storage management. Owing to the potential distributed and pervasive storage facility, it lacks efficiency towards fully preserving the integrity of user data attributes. Thereby, the collaborative sharing of user data leads to a situation which opens up various forms of security loop-holes. In the past various forms of security protocols are witnessed which have attempted to solve this similar issue with cryptographic solutions but at the same time lacks sustainability and robustness from a computational perspective. Thereby, the study introduces a 2-tier framework which offers higher-degree of access control along with Virtual Machine (VM) storage security. The study basically optimizes the performance of the model by speeding up the authentication process. The performance validation of the system has been done with respect to conventional encryption standards. The outcome obtained demonstrate that the proposed solution outperforms the existing security standards in terms of processing time, time to generate a secret key and key size for encryption.

“…Therefore, the method is infeasible. Zhihua Xia[ 28 ] presented an attribute-based access control project with valid revocation in cloud computing. The revocation is implemented using the version number of the private key, and the scheme also supports the backward security and forward security.…”

Searchable and revocable multi-data owner attribute-based encryption scheme with hidden policy in cloud storage

With the development of outsourcing data services, data security has become an urgent problem that needs to be solved. Attribute-based encryption is a valid solution to data security in cloud storage. There is no existing scheme that can guarantee the privacy of access structures and achieve attribute-based encryption with keyword search and attribute revocation. In this article, we propose a new searchable and revocable multi-data owner attribute-based encryption scheme with a hidden policy in cloud storage. In the new scheme, the same access policy is used in both the keyword index and message encryption. The advantage of keyword index with access policy is that as long as a user’s attributes satisfy the access policy, the searched ciphertext can be correctly decrypted. This property improves the accuracy of the search results. The hidden policy is used in both the ciphertext and the keyword index to protect users’ privacy. The new scheme contains attribute revocation, which is suitable for the actual situation that a user’s attributes maybe changed over time. In the general bilinear group model, the security of the scheme is demonstrated, and the efficiency of the scheme is analyzed.
