Attribute based data sharing with attribute revocation

Proceedings of the 5th ACM Symposium on Information, Computer and Communications Security, 2010
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 access structures on attributes.

Attributes revocation through ciphertext puncturation

Journal of Information Security and Applications, 2019
Abstract In order to solve the difficult issue of attribute revocation in the attribute based encryption scheme, a novel method of revoking attributes through ciphertext puncturation is proposed. In this method, a ciphertext puncturation algorithm is designed and the “NOT” operator’s ability to negate attributes in the non-monotonic access policy is ...

Multi-authority Attribute Based Encryption with Attribute Revocation

2014 IEEE 17th International Conference on Computational Science and Engineering, 2014
Multi authority attribute based encryption solve a completely trust problem about a single authorization center, make the data owner control fine-grained data and resist collusion attack. But in the practical attribute revocation needs a lot of calculation. Adding the user revocation list into cipher text implements the user revocation.

An Attribute Revocable CP-ABE Scheme

2019 Seventh International Conference on Advanced Cloud and Big Data (CBD), 2019
Ciphertext storage can effectively solve the security problems in cloud storage, among which the ciphertext policy attribute-based encryption (CP-ABE) is more suitable for ciphertext access control in cloud storage environment for it can achieve one-to-many ciphertext sharing. The existing attribute encryption scheme CP-ABE has problems with revocation

Attribute-Based Signatures with Efficient Revocation

2013 5th International Conference on Intelligent Networking and Collaborative Systems, 2013
Based signatures (ABS for short) allow an entity to sign messages with a fine-grained control over identity information. The signature attests not to the identity of the individual who endorsed a message, but instead to a claim regarding the attributes he/she holds.

Immediate Attribute Revocation in Decentralized Attribute-Based Encryption Access Control

2017 IEEE Trustcom/BigDataSE/ICESS, 2017
Access control is one of the most challenging issues in Cloud environment, it must ensure data confidentiality through enforced and flexible access policies. The revocation is an important task of the access control process, generally it consists on banishing some roles from the users.
