PPDCP-ABE: Privacy-Preserving Decentralized Cipher-Policy Attribute-Based Encryption
Cipher-policy attribute-based encryption (CP-ABE) is a more efficient and flexible encryption system as the encryptor can control the access structure when encrypting a message. In this paper, we propose a privacy-preserving decentralized CP-ABE (PPDCP-ABE) scheme where the central authority is not required, namely each authority can work independently without the cooperation to initialize the ...
متن کاملKey-Policy Multi-authority Attribute-Based Encryption
Bilinear groups are often used to create Attribute-Based Encryption (ABE) algorithms. In particular, they have been used to create an ABE system with multi authorities, but limited to the ciphertext-policy instance. Here, for the first time, we propose two multi-authority key-policy ABE systems. In our first proposal, the authorities may be set up in any moment and without any coordination. A p...
متن کاملQuantum Key-Policy Attribute-Based Encryption
Attribute-Based Encryption is a relatively new concept in the field of cryptography, and it allows only the authorized entities to decrypt a message. This type of encryption is the mechanism by which the users may encrypt and decrypt data based on user attributes. This paper proposes the first quantum alternative of the scheme Key-Policy Attribute Based Encryption, where the information, the en...
متن کاملA key-policy attribute-based broadcast encryption
According to the broadcast encryption scheme with wide applications in the real world without considering its security and efficiency in the model simultaneously an “unbounded”, Key-Policy Attribute-Based Broadcast Encryption scheme(KP-ABBE) was proposed by combining with waters dual system encryption, attribute-based encryption and broadcast encryption system. Based on the standard model, the ...
متن کاملIR-CP-ABE: Identity Revocable Ciphertext-Policy Attribute-Based Encryption for Flexible Secure Group-Based Communication
Ciphertext-Policy Attribute-Based Encryption (CP-ABE) is an access control mechanism over encrypted data and well suited for secure group-based communication. However, it also suffers from the following problem, i.e., it is impossible to build all desired groups. For example, if two group members have exactly the same attributes, how to construct a group including only one of the two members? O...
