Research on Ciphertext-Policy Attribute-Based Encryption with Attribute Level User Revocation in Cloud Storage

, 2017
Attribute-based encryption (ABE) scheme is more and more widely used in the cloud storage, which can achieve fine-grained access control. However, it is an important challenge to solve dynamic user and attribute revocation in the original scheme.

towards attribute revocation in key-policy attribute based encryption

, 2011
National Natural Science Foundation of China (NSFC); Shandong University (SDU)Attribute revocation is important to the attribute-based encryption (ABE). The existing ABE schemes supporting revocation mainly focus on the revocation of the user's identity,

an attribute based encryption scheme with fine-grained attribute revocation

, 2012
As a new public key primitive, attribute-based encryption (ABE) is envisioned to be a promising tool for implementing fine-grained access control. When applying ABE schemes to practical applications, revocation mechanism is very necessary for any ABE ...

Time-based and privacy protection revocable and traceable data sharing scheme in cloud computing

Tongxin xuebao, 2021
General ciphertext-policy attribute-based encryption (CP-ABE) provides fine-grained access control for data sharing in cloud computing, but its plaintext formed access policy may cause leakage of private and sensitive data.And revoking a malicious user ...

Trust model for certificate revocation in Ad hoc networks [PDF]

, 2007
In this paper we propose a distributed trust model for certificate revocation in Adhoc networks. The proposed model allows trust to be built over time as the number of interactions between nodes increase.

Efficient revocable attribute-based encryption scheme

Tongxin xuebao, 2019
In the existing solutions,the time-based scheme is difficult to achieve immediate revocation,and the third-party-based scheme often requires re-encryption,which needs large amount of calculation and doesn’t apply to mas-sive data.To solve the problem,an ...
