• Securely Outsourcing Attribute-Based Encryption with Checkability (2014, methodology): “A construction of KP-ABE was provided in the same paper [6], while the first CP-APE construction supporting tree-based structure in generic group model is presented by Bethencourt et al. [7].”
• Provably secure ciphertext policy ABE (2007, methodology): “We also point out that our CPA security game is weaker than that of [1], because the adversary must submit a challenge access structure before the setup phase.”
• Cryptographic Cloud Storage (2010, neutral): “Improved constructions are given in [25, 27, 10].”
• Cloud computing security: The scientific challenge, and a survey of solutions (2013, methodology): “Excalibur consists of 22K lines of C code, including the monitor, the clientside library, the client-side demon for securing CPABE decryption keys, the management console, and the certificate toolkit.”
• Secure attribute-based systems (2006, background): “Techniques from hierarchical identity-based cryptography (HIBE) [18,20,24] or advances in the cryptographic primitives [6] may help to alleviate the policy and management complexity issues discussed above.”
• A Survey on Access Control in the Age of Internet of Things (2020, background): “ABE mainly consists of key-policy ABE (KP-ABE) [37] or ciphertext-policy ABE (CP-ABE) [38].”
• Improving privacy and security in multi-authority attribute-based encryption (2009, methodology): “If it turns out that this is the author­ity from which the adversary requests insu.cient attributes for user u, then we are all set, and we can simply reuse the Sahai-Waters techniques.”
• Multi-Input Functional Encryption (2014, background): “Functional encryption [10, 21, 17], which extends the earlier notion of predicate encryption (aka, attribute-based encryption) [25, 11, 6, 27], offers much more fine-grained control.”
• Attribute-Based Access Control with Efficient Revocation in Data Outsourcing Systems (2011, background): “1, the architecture of the data outsourcing system consists of the following entities: 1.”
• A Review on the State-of-the-Art Privacy-Preserving Approaches in the e-Health Clouds (2014, background): “Ciphertext policy attribute-based encryption (CP-ABE)— first introduced in [74], a message in the CP-ABE is encrypted under an access policy that defines the access structure, whereas the users’ private keys are associated with a set of attributes.”
• Hierarchical Predicate Encryption for Inner-Products (2009, background): “The notion of predicate encryption (PE) was explicitly presented by Katz, Sahai and Waters [16] as a generalized (fine-grained) notion of encryption that covers identity-based encryption (IBE) [2,3,5,9,10,15], hidden-vector encryption (HVE) [7] and attribute-based encryption (ABE) [1,13,19,20,21].”
• Internet of things security: A top-down survey (2018, background): “A legitimate user is a user who holds a set of su ffi cient attributes I that satisfies the access structure (policy A ) attached to the ciphertext [16] (see figure 5).”
• Securing Fog Computing for Internet of Things Applications: Challenges and Solutions (2018, background): “have been proposed [134], [135], which can be divided into two categories: ciphertext-policy attribute-based encryption (CP-ABE) [134] and key-policy attribute-based encryption (KP-ABE) [135].”
• KSF-OABE: Outsourced Attribute-Based Encryption with Keyword Search Function for Cloud Storage (2017, methodology): “In CP-ABE scheme, a malicious user maybe shares his attributes with other users, which might leak his decryption privilege as a decryption blackbox due to financial profits.”
• Data security and privacy in wireless body area networks (2010, methodology): “Ciphertext Policy ABE (CP-ABE) [ 10 ] perfectly matches the model of RBAC.”
• Attribute-Based Encryption with Partially Hidden Encryptor-Specified Access Structures (2008, methodology): “By building on the previous schemes [2, 11], we can also realize collusion-resistant CP-ABE schemes.”
