Partially policy hidden CP-ABE supporting dynamic policy updating [PDF]
Tongxin xuebao, 2015 Ciphertext-policy attribute-based encryption (CP-ABE) was considered to be appropriate for cloud storage.However,under traditional CP-ABE scheme which was limited in terms of the scale of the data and the quantities of the attributes,computation and ...

CP-ABE With Constant-Size Keys for Lightweight Devices
IEEE Transactions on Information Forensics and Security, 2014 Lightweight devices, such as radio frequency identification tags, have a limited storage capacity, which has become a bottleneck for many applications, especially for security applications. Ciphertext-policy attribute-based encryption (CP-ABE) is a promising cryptographic tool, where the encryptor can decide the access structure that will be used to ...

Instantaneous Proxy-Based Key Update for CP-ABE
2016 IEEE 41st Conference on Local Computer Networks (LCN), 2016 Attribute Based Encryption (ABE) scheme has been proposed to implement cryptographic fine grained access control to shared information. It allows to share information of type one-to-many users, without considering the number of users and their identities.

Efficient pairing-free CP-ABE based on ordered binary decision diagram [PDF]
Tongxin xuebao, 2019 To improve the computational efficiency of ABE,its access structure was optimized and a pairing-free CP-ABE scheme based on ordered binary decision diagram (OBDD) was proposed.Based on the elliptic curve cryptography,the complex bilinear pairing ...

Key public verifiable MA-CP-ABE scheme based on aggregatable PVSS and consortium blockchain [PDF]
Tongxin xuebaoTo address challenges associated with threshold-based multi-authority ciphertext-policy attribute-based encryption (MA-CP-ABE), such as untrusted attribute authorities (AA) and the inability to verify the correctness of attribute private keys publicly, a

Provably Secure Ciphertext-Policy Attribute-Based Encryption from Identity-Based Encryption [PDF]
Journal of Universal Computer Science, 2019 Ciphertext-policy attribute-based encryption (CP-ABE) is an access control mechanism where a data provider encrypts a secret message and then sends the ciphertext to the receivers according to the access policy which she/he decides.

Attribute-based encryption schema with group signatures
网络与信息安全学报, 2019 Cipher text-policy attribute-based encryption schema(CP-ABE) is widely used in protection of sensitive data.In CP-ABE,When the users access the cipher text,the access structure and the cipher text were sent to the users.However,the access structure is ...

Updating attribute in CP-ABE: A New Approach
IACR Cryptol. ePrint Arch., 2012 In Ciphertext-Policy Attribute Based Encryption (CP-ABE), attributes are attached to the user's secret key and access policy is at-tached to the ciphertext. If attributes in the secret key of a user satisfy the policy then only the genuine user can decrypt the ciphertext. However, such scenario also necessitates periodic updating of the secret key with
