Removing escrow from ciphertext policy attribute-based encryption
Computers and Mathematics With Applications, 2013 Abstract Attribute-based encryption (ABE) is a promising cryptographic primitive for fine-grained access control of distributed data. In ciphertext policy attribute-based encryption (CP-ABE), each user is associated with a set of attributes and data are encrypted with access policies on attributes.

Ciphertext policy-hiding attribute-based encryption
2015 International Conference on Advances in Computing, Communications and Informatics (ICACCI), 2015Ciphertext-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 ...

Ciphertext policy attribute-based encryption from lattices
Proceedings of the 7th ACM Symposium on Information, Computer and Communications Security, 2012Sahai 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 ...

Server Aided Ciphertext-Policy Attribute-Based Encryption
2015 IEEE 29th International Conference on Advanced Information Networking and Applications Workshops, 2015Attribute-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

Securely outsourcing the ciphertext-policy attribute-based encryption
World Wide Web, 2017Attribute-based Encryption (ABE) is a new and promising public key encryption that allows fine-grained authorization on data based on user attributes. Such property is favorable for multiple applications that require encrypted storage or access control on data, in particular: eHealth applications.

GPU Acceleration of Ciphertext-Policy Attribute-Based Encryption
2019 20th IEEE/ACIS International Conference on Software Engineering, Artificial Intelligence, Networking and Parallel/Distributed Computing (SNPD), 2019With the development of cloud computing, data security became popular in recent decades. However, traditional cryptography has some major limitations. For example, public key cryptography is not scalable in cases with many clients. Since Ciphertext-Policy Attribute-based encryption (CP-ABE) was developed in 2007, it has become as one of the major ...

Bounded Ciphertext Policy Attribute Based Encryption
2008In 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.

Privacy Preserving Ciphertext Policy Attribute Based Encryption
2010Ciphertext policy attribute based encryption (CP-ABE) allows to encrypt data under an access policy. The access policy can be formed with the logical combination of attributes.. Such ciphertexts can be decrypted by anyone with a set of attributes that satisfy the access policy. In CP-ABE, access policy is sent along with the ciphertext.
