An Outsourced Attribute-Based Encryption Scheme Supporting Attribute Revocation [PDF]
Jisuanji gongcheng, 2017 Traditional Ciphertext-Policy Attribute-Based Encryption(CP-ABE) schemes have large computational overhead in key generation,decryption and attribute revocation processes.Aiming at this problem,this paper proposes an outsourced CP-ABE scheme which ...

Adaptable Ciphertext-Policy Attribute-Based Encryption
, 2014 In this paper, we introduce a new cryptographic primitive, called adaptable ciphertext-policy attribute-based encryption CP-ABE. Adaptable CP-ABE extends the traditional CP-ABE by allowing a semi-trusted proxy to modify a ciphertext under one access policy into ciphertexts of the same plaintext under any other access policies; the proxy, however ...

An Attribute-based Encryption Scheme for Ciphertext Policy that Supports Attribute Revocation [PDF]
Jisuanji gongcheng, 2021 The traditional single-authorization Attribute-Based Encryption(ABE) schemes are limited by the high computing overhead and the poor security.Based on secure two-party computing protocols,this paper proposes a multi-authorization ciphertext policy ABE ...

Insecurity of A Key-Policy Attribute Based Encryption Scheme With Equality Test
IEEE Access, 2018 Attribute-based encryption is a popular cryptographic technology to protect the privacy of clients' data in cloud computing. In order to make the scheme have the functionality of comparing ciphertext, Zhu et al. combined concepts of key-policy attributed-

ON MULTI-AUTHORITY CIPHERTEXT-POLICY ATTRIBUTE-BASED ENCRYPTION [PDF]
Bulletin of the Korean Mathematical Society, 2009 In classical encryption schemes, data is encrypted under a single key that is associated with a user or group. In Ciphertext-Policy Attribute-Based Encryption(CP-ABE) keys are associated with attributes of users, given to them by a central trusted authority, and data is en- crypted under a logical formula over these attributes.

An Enhanced Approach for CP-ABE with Proxy Re-encryption in IoT Paradigm
Jordanian Journal of Computers and Information Technology, 2022 In Internet of Things (IoT), encryption is a technique in which plaintext is converted to ciphertext to make it non-recovered by the attacker without secret key.

Ciphertext policy Attribute based Encryption with anonymous access policy
International Journal of Peer to Peer Networks, 2010 In Ciphertext Policy Attribute based Encryption scheme, the encryptor can fix the policy, who can decrypt the encrypted message. The policy can be formed with the help of attributes. In CP-ABE, access policy is sent along with the ciphertext. We propose a method in which the access policy need not be sent along with the ciphertext, by which we are able
