CP-ABE Scheme Using Selectively Hidden Tree Access Structure [PDF]

Jisuanji gongcheng, 2020
Hidden access structure is a secure operation of Ciphertext Policy Attribute Base Encryption(CP-ABE),which can effectively prevent the leakage of sensitive information.However,tree access structure used by existing CP-ABE schemes are either completely ...

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.

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.

Palmitoylation of PSD‐95 Orchestrates Learning‐Dependent Metaplasticity in the Amygdala and Fear Memory

Advanced Science, EarlyView.
This study reveals that fear learning specifically triggers PICK1/DHHC2‐dependent palmitoylation of PSD‐95 in the lateral amygdala. Fear conditioning induces the dissociation of DHHC5 from PSD‐95 and the association of PSD‐95 with DHHC2. DHHC2‐mediated palmitoylation of PSD‐95 is required for synaptic transmission and underlies fear learning–induced ...

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

Nutritional properties, traditional uses and potential new applications for the sotol plant (Asparagaceae, Convallarioideae): A review

PLANTS, PEOPLE, PLANET, EarlyView.
Sotol (Dasylirion spp.) is a resilient desert plant that sustains ecosystems, cultures and livelihoods in Chihuahua Desert. Our review highlights its nutritional properties, traditional uses and potential new applications in food, pharmaceuticals, renewable energy and water remediation. By synthesizing evidence across disciplines, we show how sotol can
