Ciphertext policy attribute-based encryption scheme supporting direct revocation

Tongxin xuebao, 2016
In order to support fine-grained attribute revocation in direct revocation mode an attribute-based encryption scheme with efficient revocation was proposed.The model of ABE supporting attribute revocation was given,and a con-crete scheme was constructed ...

An Adaptively CCA-Secure Ciphertext-Policy Attribute-Based Proxy Re-Encryption for Cloud Data Sharing

, 2014
A Ciphertext-Policy Attribute-Based Proxy Re-Encryption (CP-ABPRE) employs the PRE technology in the attribute-based encryption cryptographic setting, in which the proxy is allowed to convert an encryption under an access policy to another encryption ...

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.

A ciphertext-policy attribute-based proxy re-encryption scheme for data sharing in public clouds

, 2014
Ciphertext-policy attribute-based proxy re-encryption (CP-ABPRE) extends the traditional Proxy Re- Encryption (PRE) by allowing a semi-trusted proxy to transform a ciphertext under an access policy to another ciphertext with the same plaintext under a ...
