Attack and defense techniques in large language models: A survey and new perspectives Open

Zhongxing Liao, Kang Chen, Yuanjie Lin, K. Li, Y.Z. Liu , et al. · 2025

Large Language Models (LLMs) have become central to numerous natural language processing tasks, but their vulnerabilities present significant security and ethical challenges. This systematic survey explores the evolving landscape of attack…

Unordered Multisecret Sharing Based on Generalized Chinese Remainder Theorem Open

Xiaoping Li, Hefeng Chen, Yanjun Liu, Chin‐Chen Chang · 2020

Multisecret sharing schemes have been widely used in the area of information security, such as cloud storage, group authentication, and secure parallel communications. One of the issues for these schemes is to share and recover multisecret…

An Improved Bidirectional Shift-Based Reversible Data Hiding Scheme Using Double-Way Prediction Strategy Open

Lin Li, Chin‐Chen Chang, Hefeng Chen · 2019

Reversible data hiding (RDH) is a method that allows a cover image to be completely recovered from its corresponding stego image without distortion after the embedded secret messages have been extracted. Prediction-error expansion (PEE), a…

A Novel Secret Sharing Scheme Based upon Euler’s Theorem Open

Hefeng Chen, Chin‐Chen Chang · 2019

The secret sharing scheme is used to protect the privacy of information by distribution. More specifically, a dealer splits a secret into n shares and distributes them privately to n participants, in such a way that any t or more particip…

A Secret Image Restoring Scheme Using Threshold Pairs of Unordered Image Shares Open

Xiaoping Li, Yanjun Liu, Hefeng Chen, Chin‐Chen Chang · 2019

Secret image sharing has been widely used in numerous areas such as remote sensing and information security. The goal is to share and recover one or more images using several image shares. However, most schemes only consider ordered shares…

Liveness of Disjunctive and Strict Single-Type Automated Manufacturing System: An ROPN Approach Open

Hefeng Chen, Naiqi Wu, Zhiwu Li, Ting Qu, Hailian Xiao · 2019

The resource-oriented Petri net (ROPN) modeling method is applied in this paper to model a class of automated manufacturing systems (AMS) named disjunctive and strict single-type AMSs (DS-AMS), where multiple units of a single resource typ…
