Ciphertext policy-hiding attribute-based encryption

2015 International Conference on Advances in Computing, Communications and Informatics (ICACCI), 2015
Ciphertext-policy attribute based encryption (CP-ABE) is becoming very important in distributed computing environment, because it makes easier to protect, broadcast and control the access of information, especially over the cloud server. In CP-ABE every plaintext is encrypted under an access structure, defined on the user's attribute and users have ...

Server Aided Ciphertext-Policy Attribute-Based Encryption

2015 IEEE 29th International Conference on Advanced Information Networking and Applications Workshops, 2015
Attribute-based encryption (ABE) is a type of public key encryption that allows users to encrypt and decrypt messages based on user attributes. One drawback is that encryption and decryption computational costs scale with the complexity of the access policy or number of attributes. In practice, this makes encryption and decryption a possible bottleneck

Ciphertext policy attribute-based encryption from lattices

Proceedings of the 7th ACM Symposium on Information, Computer and Communications Security, 2012
Sahai and Waters [6] proposed Attribute-Based Encryption (ABE) as a new paradigm of encryption algorithms that allow the sender to set a policy describing who can decrypt a particular ciphertext. In this paper, we first propose a ciphertext policy attribute-based encryption (CP-ABE) scheme from lattices, which supports flexible threshold access ...

Bounded Ciphertext Policy Attribute Based Encryption

2008
In a ciphertext policy attribute based encryption system, a user's private key is associated with a set of attributes (describing the user) and an encrypted ciphertext will specify an access policy over attributes. A user will be able to decrypt if and only if his attributes satisfy the ciphertext's policy.
