VB-CP-ABE: An Improved CP-ABE Scheme Based on Blockchain Collaboration and Fine-Grained Version Control

Journal of Computing and Electronic Information Management
To address the shortcomings of data privacy protection in fruit traceability systems and the high revocation overhead of traditional CP-ABE schemes when personnel changes are frequent, this paper proposes an improved traceability system based on blockchain collaboration and version control.

Fuzzy matching and direct revocation: a new CP-ABE scheme from multilinear maps

, 2018
© 2017, Springer-Verlag Berlin Heidelberg. In the attribute-based encryption (ABE) systems, users could encrypt and decrypt messages based on some attributes or access policies. Due to the functionality and flexibility of ABE, it is considered to be very

Efficient and Secure Access Control Scheme in the Standard Model for Vehicular Cloud Computing

IEEE Access, 2018
Vehicular networking involves the storage, compute, and analysis of massive vehicular data. Vehicular cloud computing, as a special cloud computing platform, seamlessly combines vehicular ad hoc networks and conventional cloud computing.

White-Box Traceable Ciphertext-Policy Attribute-Based Encryption in Multi-Domain Environment

IEEE Access, 2019
In a ciphertext-policy attribute-based encryption (CP-ABE) system, the decryption keys are only related to attributes shared by multiple users and do not contain any identity information of their original holders.

Large Universe CP-ABE With Whitebox Traceability

International Journal on Cybernetics & Informatics, 2016
In a ciphertext-policy attribute-based encryption (CP-ABE) system, decryption keys are defined over attributes shared by multiple users. Traceability is the ability of ABE to trace the malicious users or traitors who intentionally leak the partial or modified decryption keys for profits.

Traceable CP-ABE on Prime Order Groups: Fully Secure and Fully Collusion-resistant Blackbox Traceable [PDF]

, 2015
. In Ciphertext-Policy Attribute-Based Encryption (CP-ABE), access policies associated with the ciphertexts are generally role-based and the attributes satisfying the policies are generally shared by multiple users.

Secure Pairing-Free IBE and CP-ABE from Inner-Product Functional Encryption [PDF]

The potential of Attribute-Based Encryption (ABE) in the context of IoT has driven researchers to propose pairing-free ABE schemes that are suitable for resource-constrained devices. Unfortunately, many of these schemes turned out to be insecure.

cp-abe scheme supporting fully fine-grained attribute revocation

, 2012
属性撤销是基于属性的加密(attribute based encryption,简称ABE)在实际应用中所必须解决的问题.在直接撤销模式下,已有的支持属性撤销的ABE方案只能以撤销用户身份的方式对用户所拥有的全部属性进行撤销,而无法做到针对属性的细粒度撤销.提出了直接模式下支持完全细粒度属性撤销的CP-ABE(cipher policy ABE)模型,在合数阶双线性群上,基于双系统加密的思想构造了具体的方案,并在标准模型下给出了严格的安全性证明.该方案能够对用户所拥有的任意数量的属性进行撤销 ...
