Multi-authority based CP-ABE proxy re-encryption scheme for cloud computing
网络与信息安全学报, 2022 Proxy re-encryption allows a proxy to convert a ciphertext related to a certain access policy into another one with a different access policy without uncovering the underlying plaintext, which makes the proxy re-encryption technology to be an important ...

Data Querying with Ciphertext Policy Attribute Based Encryption
CoRR, 2022 Data encryption limits the power and efficiency of queries. Direct processing of encrypted data should ideally be possible to avoid the need for data decryption, processing, and re-encryption. It is vital to keep the data searchable and sortable. That is, some information is intentionally leaked.

CP-ABE Scheme with Attribute Revocation Under Environment of Multi-attribute Authority [PDF]
Jisuanji gongcheng, 2018 For the attribute-based encryption scheme,a single authority has the problem of low efficiency and easy disclosure of user keys.Through the establishment of a decentralized attribute authority and agent reencryption technology,a Ciphertext-policy ...

Ciphertext-Policy Attribute-Based Broadcast Encryption Scheme [PDF]
, 2011 In this work, we design a new attribute-based encryption scheme with the revocation capability. In the proposed schemes, the user (broadcaster) encrypts the data according to an access policy over the set of attributes, and a list of the identities of revoked users.
