Using Predicate Extension for Predicate Encryption to Generically Obtain Chosen-Ciphertext Security and Signatures [PDF]

IACR Communications in Cryptology
Predicate encryption (PE) is a type of public-key encryption that captures many useful primitives such as attribute-based encryption (ABE). Although much progress has been made to generically achieve security against chosen-plaintext attacks (CPA ...

Collusion-Resistant Processing of SQL Range Predicates

Data Science and Engineering, 2018
Prior solutions for securely handling SQL range predicates in outsourced Cloud-resident databases have primarily focused on passive attacks in the Honest-but-Curious adversarial model, where the server is only permitted to observe the encrypted query ...

An Inner Product Predicate-Based Medical Data-Sharing and Privacy Protection System

IEEE Access
Searchable encryption is widely used in electronic health record systems because it enables users to search ciphertext data without decryption. However, the existing traditional searchable encryption schemes lack fine-grained access policies with ...

Predicate-based authenticated key exchange protocol with attribute-hiding

Tongxin xuebao, 2012
To overcome the problem that available predicate-based authenticated key exchange(PBAKE)protocols had drawback on privacy protection,a new PBAKE protocol was presented.The new protocol was constructed via combining an inner product encryption scheme with

Predicate Encryption for Secure Remote Storage [PDF]

, 2010
Predicate encryption is a special encryption method that allows one to release keys to compute specific predicates of the plaintext without having to decrypt. This cryptographic primitive is instrumental for executing search on encrypted data and enables remote storage of data.

Liquid Crystalline Elastomers in Soft Robotics: Assessing Promise and Limitations

Advanced Robotics Research, EarlyView.
Liquid crystalline elastomers (LCEs) are programmable soft materials that undergo large, anisotropic deformation in response to external stimuli. Their molecular alignment encodes directional actuation in a monolithic structure, making them long‐standing candidates for soft robotic systems.

Transferable Deep Reinforcement Learning With Edge‐Contour‐Depth Fusion for Autonomous Wireless Capsule Endoscopy Navigation

Advanced Science, EarlyView.
This study presents an anatomical landmark‐guided DRL framework for autonomous wireless capsule endoscopy navigation. Using a lightweight edge‐contour‐depth fusion module, it achieves over 97% coverage across diverse gastric anatomies. To ensure reliability, a two‐stage sim‐to‐real pipeline with an adaptive dynamic programming controller mitigates ...

Sampling Strategy: An Overlooked Factor Affecting Artificial Intelligence Prediction Accuracy of Peptides’ Physicochemical Properties

Advanced Intelligent Discovery, EarlyView.
This study reveals that sampling strategy (i.e., sampling size and approach) is a foundational prerequisite for building accurate and generalizable AI models in peptide discovery. Reaching a threshold of 7.5% of the total tetrapeptide sequence space was essential to ensure reliable predictions.
