Efficient revocable attribute-based encryption scheme
Tongxin xuebao, 2019 In the existing solutions,the time-based scheme is difficult to achieve immediate revocation,and the third-party-based scheme often requires re-encryption,which needs large amount of calculation and doesn’t apply to mas-sive data.To solve the problem,an ...

Attribute-based encryption scheme supporting attribute revocation in cloud storage environment
Tongxin xuebao, 2019 Attribute-based encryption (ABE) scheme is widely used in the cloud storage due to its fine-grained access control.Each attribute in ABE may be shared by multiple users at the same time.Therefore,how to achieve attribute-level user revocation is ...

Revocable attribute-based proxy re-encryption [PDF]
Journal of Mathematical Cryptology, 2021 Abstract Attribute-based proxy re-encryption (ABPRE), which combines the notions of proxy re-encryption (PRE) and attribute-based encryption (ABE), allows a semi-trusted proxy with re-encryption key to transform a ciphertext under a particular access policy into a ciphertext under another access policy, without revealing any information ...
