Ciphertext-Policy Attribute-Based Encryption [PDF]
2007 IEEE Symposium on Security and Privacy (SP '07), 2007 In several distributed systems a user should only be able to access data if a user posses a certain set of credentials or attributes. Currently, the only method for enforcing such policies is to employ a trusted server to store the data and mediate access control.

Removing escrow from ciphertext policy attribute-based encryption [PDF]
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.

Efficient ciphertext-policy attribute-based encryption with blackbox traceability
Information Sciences, 2020 Traitor tracing scheme is a paradigm to classify the users who illegal use of their decryption keys in cryptosystems. In the ciphertext-policy attribute-based cryptosystem, the decryption key usually contains the users’ attributes, while the real ...
