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.

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

Achieving Flexible and Self-Contained Data Protection in Cloud Computing
IEEE Access, 2017 For enterprise systems running on public clouds in which the servers are outside the control domain of the enterprise, access control that was traditionally executed by reference monitors deployed on the system servers can no longer be trusted.

A Cluster of CP-ABE Microservices for VANET
Procedia Computer Science, 2019 Abstract The promising high data rate of a 5G network enables the reality of Vehicular Ad Hoc Networks (VANET). VANETS are ad-hoc networks and they have limited resources. Providing the confidentiality of data by an access control system in a highly dynamic and automated network is a major challenge.

Expressive CP-ABE with partially hidden access structures
Proceedings of the 7th ACM Symposium on Information, Computer and Communications Security, 2012 At Eurocrypt 2005, Sahai and Waters [7] introduced the concept of attribute-based encryption (ABE). ABE enables public key based one-to-many encryption and is envisioned as a promising cryptographic primitive for realizing scalable and fine-grained access control systems.
