Time-Based Direct Revocable Ciphertext-Policy Attribute-Based Encryption with Short Revocation List [PDF]
Lecture Notes in Computer Science, 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 ...

Blockchain-Enhanced Data Sharing With Traceable and Direct Revocation in IIoT
IEEE Transactions on Industrial Informatics, 2021The industrial Internet of Things (IIoT) supports recent developments in data management and information services, as well as services for smart factories. Nowadays, many mature IIoT cloud platforms are available to serve smart factories. However, due to the semicredibility nature of the IIoT cloud platforms, how to achieve secure storage, access ...

FDR-ABE: Attribute-Based Encryption with Flexible and Direct Revocation
2013 5th International Conference on Intelligent Networking and Collaborative Systems, 2013In attribute-based encryption (ABE) systems, the revocation issue is essential and difficult, since users may change their attributes frequently in practice and each attribute is conceivably shared by multiple users. To our knowledge, all the existing ABE schemes fail to support flexible and direct revocation due to the burdensome update of attribute ...

Direct Anonymous Attestation in practice: Implementation and efficient revocation
2014 Twelfth Annual International Conference on Privacy, Security and Trust, 2014Direct Anonymous Attestation (DAA) is a signature scheme that provides a balance between user privacy and authentication in a reasonable way. The first RSA-based DAA is proposed in 2004, since then several ECC-based DAA schemes are proposed to achieve better performance. To analyze DAA schemes from a practical point of view, it is necessary to consider

Hierarchy attribute-based encryption scheme to support direct revocation in cloud storage
2017 IEEE/ACIS 16th International Conference on Computer and Information Science (ICIS), 2017Attribute-Based Encryption Scheme solves the security problems faced by cloud storage. In many practical applications, the files encrypted by Attribute-Based Encryption have the characteristics of multiple levels. However, CP-ABE cannot encrypt the data according to the level.

Attribute-Based Proxy Re-Encryption With Direct Revocation Mechanism for Data Sharing in Clouds
IEEE Transactions on Dependable and Secure Computing, 2023Cloud computing, which provides adequate storage and computation capability, has been a prevalent information infrastructure. Secure data sharing is a basic demand when data was outsourced to a cloud server. Attribute-based proxy re-encryption has been a promising approach that allows secure encrypted data sharing on clouds.
