Attribute Revocable Attribute-Based Encryption for Decentralized Disruption-Tolerant Military Networks

2015 Third International Symposium on Computing and Networking (CANDAR), 2015
Disruption-tolerant network technologies are becoming solutions to access the confidential information or command by exploiting external storage node. It is necessary to encrypt the shared data to prevent illegal access to ciphertext by the third party.

Efficient Attribute Revocation Scheme for Multi-authority Attribute Cloud Storage System

2016 International Conference on Information Technology (ICIT), 2016
Cloud computing is an emerging computing tool in which resources accessed as a service over Internet on pay for use basis. Most of the organization are changing their storage server to cloud server without any botheration. It is a great challenge for the cloud service provider to attract the customers to store their sensitive data/file in the cloud ...

A Revocable Outsourcing Attribute-Based Encryption Scheme

2017
Attribute-Based Encryption (ABE) is a generalized cryptographic primitive from normal public key encryption. It provides an access control mechanism over encrypted message using access policies and ascribed attributes. This scheme can solve the privacy issue when data is outsourced to cloud for storage well.

Time-Based Direct Revocable Ciphertext-Policy Attribute-Based Encryption with Short Revocation List

2018
In this paper, we propose an efficient revocable Ciphertext-Policy Attribute-Based Encryption (CP-ABE) scheme. We base on the direct revocation approach, by embedding the revocation list into ciphertext. However, since the revocation list will grow longer as time goes by, we further leverage this by proposing a secret key time validation technique so ...

A Policy Revocation Scheme for Attributes-based Encryption

Proceedings of the 10th International Conference on Advances in Information Technology, 2018
Attributes-based encryption (ABE) is a promising cryptographic mechanism that provides a fine-grained access control for cloud environment. Since most of the parties exchange sensitive data among them by using cloud computing, data protection is very important for data confidentiality.

Attribute-Based Encryption Supporting Direct/Indirect Revocation Modes

2009
Attribute-based encryption (ABE) enables an access control mechanism over encrypted data by specifying access policies among private keys and ciphertexts. In this paper, we focus on ABE that supports revocation. Currently, there are two available revocable ABE schemes in the literature.
