mR$_{\text{LWE}}$-CP-ABE a revocable CP-ABE for Post-Quantum Cryptography
, 2023 We address the problem of user fast revocation in the lattice based CP-ABE by extending the scheme originally introduced in [A ciphertext policy attribute-based encryption scheme without pairings. J. Zhang, Z. Zhang - ICISC 2011].

An Improved Ciphertext-Policy Attribute-Based Encryption Scheme in Power Cloud Access Control
Applied Sciences, 2018 In power cloud environment, the existing Ciphertext-Policy Attribute-Based Encryption (CP-ABE) access control schemes, do not consider the generation of access structure and the existence of malicious users. To tackle these problems, a power cloud access

CP‐ABE with outsourced decryption and directionally hidden policy
Security and Communication Networks, 2016 AbstractCiphertext‐policy attribute‐based encryption (CP‐ABE) is a novel cryptographic primitive for access controlling. However, the existing CP‐ABE schemes are very inefficient as the decryptions involve many expensive pairing operations. Another drawback is that the access policy itself may disclose some privacies of the users.

Generalised CP and A4 family symmetry
, 2013 We perform a comprehensive study of family symmetry models based on A4 combined with the generalised CP symmetry H CP. We investigate the lepton mixing parameters which can be obtained from the original symmetry A4 ?

Trustworthy Users: Using IOTA and IPFS for Attribute Validation in CP-ABE and dCP-ABE Schemes [PDF]
, 2023 Attribute spoofing is a major security threat in information exchange solutions based on Ciphertext-Policy Attribute-Based-Encryption (CP-ABE) and distributed CP-ABE (dCP-ABE), which can compromise privacy and security.

Advanced Science, EarlyView.Hepatocellular carcinoma (HCC)‐derived extracellular vesicles (EVs) enrich the metabolic enzyme ATP‐citrate lyase (ACLY). EV‐transferred ACLY enhances palmitate biosynthesis, increases the S‐palmitoylation and stability of multiple immune checkpoint proteins, augments the cellular immunosuppressive activity, and ultimately accelerates the malignant ...

Forward-secure ciphertext-policy attribute-based encryption scheme
Tongxin xuebao, 2014 To mitigate the damage of key exposure in the context of ciphertext-policy attribute-based encryption (CP-ABE). The syntax and security model of forward-secure CP-ABE was presented. Then, a concreted forward-secure CP-ABE scheme was constructed.

Pattern of Progression of Oral Potentially Malignant Disorders From Real‐World Data: A 24‐Year Study
Head &Neck, EarlyView.ABSTRACT Background Oral potentially malignant disorder (OPMD) prognostication is limited by uncertainty of which lesions will progress and the aggressiveness of lesion progression. We defined patterns and kinetics of progression in a large cohort of OPMD subjected to serial clinical and histologic examinations. Methods This 24‐year study evaluated the
