In practice, not only the data but also the auditing ability should be transferred securely and efciently. However, we investigate and fnd that most of the existing data ownership transfer protocols only work well between two indi-viduals,and they become inefcient when dealing between two communities. The proposals for transferring tags between communities are problematic as well since, they require all members get involved or a fully trusted aggrega-torfacilitates ownership transfer, which are unrealistic in certain scenarios. To alleviate these problems, in this paper we develop a secure auditing protocol with decentralized (t, n)-threshold ownership transfer for cloud EMRs. This protocol is designed to operate efciently without requiring the mandatory participation of every user or the involve-mentof any trusted third-party. It is achieved by employing the threshold signature. Rigorous security analyses and comprehensive performance evaluations illustrate the security and practicality of our protocol. Specifcally, according to the evaluations and comparisons, the communication and computational consumption is independent of the fle size, i.e., it is constant in our protocol for both communities.展开更多

文摘This article takes listed companies in China's A-share market that underwent voluntary auditor changes from 2021 to 2024 as the research object,and empirically examines the impact of voluntary auditor changes on corporate audit fees.The research results show that:(1)voluntary auditor changes significantly reduce corporate audit fees,indicating that companies have bargaining advantages in auditor selection and can achieve cost savings by changing auditors;(2)The new regulatory regulations released in 2023 have significantly changed the audit pricing mechanism,so that voluntary changes no longer have a fee reduction effect;(3)When establishing an audit committee for a company,voluntary auditor changes can significantly reduce audit fees;(4)When state-owned enterprises voluntarily change auditors,the cost reduction effect of audit fees is more significant;(5)Voluntary auditor changes have partially mediated the cost reduction effect on audit fees by reducing the proportion of non audit services.This article provides empirical evidence for enterprises to optimize their auditor selection strategies,and also provides insights for regulatory authorities to identify irrational low price competition in the audit market and regulate pricing order.

文摘The exponential growth of the Internet of Things(IoT)has revolutionized various domains such as healthcare,smart cities,and agriculture,generating vast volumes of data that require secure processing and storage in cloud environments.However,reliance on cloud infrastructure raises critical security challenges,particularly regarding data integrity.While existing cryptographic methods provide robust integrity verification,they impose significant computational and energy overheads on resource-constrained IoT devices,limiting their applicability in large-scale,real-time scenarios.To address these challenges,we propose the Cognitive-Based Integrity Verification Model(C-BIVM),which leverages Belief-Desire-Intention(BDI)cognitive intelligence and algebraic signatures to enable lightweight,efficient,and scalable data integrity verification.The model incorporates batch auditing,reducing resource consumption in large-scale IoT environments by approximately 35%,while achieving an accuracy of over 99.2%in detecting data corruption.C-BIVM dynamically adapts integrity checks based on real-time conditions,optimizing resource utilization by minimizing redundant operations by more than 30%.Furthermore,blind verification techniques safeguard sensitive IoT data,ensuring privacy compliance by preventing unauthorized access during integrity checks.Extensive experimental evaluations demonstrate that C-BIVM reduces computation time for integrity checks by up to 40%compared to traditional bilinear pairing-based methods,making it particularly suitable for IoT-driven applications in smart cities,healthcare,and beyond.These results underscore the effectiveness of C-BIVM in delivering a secure,scalable,and resource-efficient solution tailored to the evolving needs of IoT ecosystems.
文摘Large models,such as large language models(LLMs),vision-language models(VLMs),and multimodal agents,have become key elements in artificial intelli⁃gence(AI)systems.Their rapid development has greatly improved perception,generation,and decision-making in various fields.However,their vast scale and complexity bring about new security challenges.Issues such as backdoor vulnerabilities during training,jailbreaking in multimodal rea⁃soning,and data provenance and copyright auditing have made security a critical focus for both academia and industry.

文摘Carbon dioxide is the main factor causing the greenhouse effect,and reducing carbon dioxide emissions is an important task in ecological civilization governance.The audit of outgoing officials'natural resource asset management is an audit of the natural resources within the jurisdiction of each province to ensure that senior officials implement policies to protect natural resources.Therefore,this paper empirically verifies the impact of audit outgoing officials'natural resource asset management on carbon emission reduction based on panel data of 297 prefecture-level cities in China from 2012 to 2021.The study finds that auditing outgoing officials'natural resource asset management can effectively reduce carbon dioxide emissions and achieve energy conservation and emission reduction.Further research finds that auditing outgoing officials'natural resource asset management can promote technological innovation and industrial structure optimization,providing a reference for the country to achieve carbon peaking and carbon neutrality goals and promote the green transformation and upgrading of social development.

文摘Federated learning is an important distributed model training technique in Internet of Things(IoT),in which participant selection is a key component that plays a role in improving training efficiency and model accuracy.This module enables a central server to select a subset of participants to performmodel training based on data and device information.By doing so,selected participants are rewarded and actively perform model training,while participants that are detrimental to training efficiency and model accuracy are excluded.However,in practice,participants may suspect that the central server may have miscalculated and thus not made the selection honestly.This lack of trustworthiness problem,which can demotivate participants,has received little attention.Another problem that has received little attention is the leakage of participants’private information during the selection process.We will therefore propose a federated learning framework with auditable participant selection.It supports smart contracts in selecting a set of suitable participants based on their training loss without compromising the privacy.Considering the possibility of malicious campaigning and impersonation of participants,the framework employs commitment schemes and zero-knowledge proofs to counteract these malicious behaviors.Finally,we analyze the security of the framework and conduct a series of experiments to demonstrate that the framework can effectively improve the efficiency of federated learning.
