A Survey of Attribute-based Access Control with User Revocation in Cloud Data Storage

by Chi-Wei Liu , Wei-Fu Hsien , Chou-Chen Yang , Min-Shiang Hwang , Min-Shiang Hwang
"... Abstract Cloud storage service is one of cloud services where cloud service provider can provide storage space to customers. Because cloud storage service has many advantages which include convenience, high computation and capacity, it attracts the user to outsource data in the cloud. However, the ..."

, the user outsources data directly in cloud storage service that is unsafe when outsourcing data is sensitive for the user. Therefore, ciphertext-policy attribute-based encryption is a promising cryptographic solution in cloud environment, which can be drawn up for access control by the data owner to define

Dynamic credentials and ciphertext delegation for attribute-based encryption

by Amit Sahai, Hakan Seyalioglu - in Proceedings of the 32nd Annual International Cryptology Conference: Advances in Cryptology - CRYPTO’2012 , 2012
"... Motivated by the question of access control in cloud storage, we consider the problem using Attribute-Based Encryption (ABE) in a setting where users ’ credentials may change and ciphertexts may be stored by a third party. We find that a comprehensive solution to our problem must simultaneously allo ..."

1PIRATTE: Proxy-based Immediate Revocation of ATTribute-based Encryption

by Sonia Jahid, Nikita Borisov
"... Abstract—Access control to data in traditional enterprises is typically enforced through reference monitors. However, as more and more enterprise data is outsourced, trusting third party storage servers is getting challenging. As a result, cryptography, specifically Attribute-based encryption (ABE) ..."

TAAC: Temporal Attribute-based Access Control for Multi-Authority Cloud Storage Systems

by Kan Yang, Zhen Liu, Zhenfu Cao, Xiaohua Jia, Duncan S. Wong, Kui Ren
"... Abstract—Data access control is an effective way to ensure the data security in the cloud. Due to data outsourcing and untrusted cloud servers, the data access control becomes a challenging issue in cloud storage systems. Ciphertext-Policy Attribute-based Encryption (CP-ABE), as a promising techniqu ..."

problem. In this paper, we consider the problem of attribute revocation in multiauthority cloud storage systems where the users ’ attributes come from different domains each of which is managed by a different authority. We propose TAAC (Temporal Attributebased Access Control), an efficient data access

Attribute-Based Encryption Optimized for Cloud Computing

by Máté Horváth
"... Abstract. In this work, we aim to make attribute-based encryption (ABE) more suitable for access control to data stored in the cloud. For this purpose, we concentrate on giving to the encryptor full control over the access rights, providing feasible key management even in case of multiple independen ..."

Attribute based data sharing with attribute revocation

by Shucheng Yu, Cong Wang, Kui Ren, Wenjing Lou - in Proc. of ASIACCS. ACM
"... Ciphertext-Policy Attribute Based Encryption (CP-ABE) is a promising cryptographic primitive for fine-grained access control of shared data. In CP-ABE, each user is associated with a set of attributes and data are encrypted with ac-cess structures on attributes. A user is able to decrypt a ciphertex ..."
