Cloud storage system provides facilitative file and sharing services for distributed clients. To address integrity, controllable outsourcing, origin auditing concerns on outsourced files, we propose an identity-based data outsourcing (IBDO) scheme equipped with desirable features advantageous over existing proposals in securing data. First, our IBDO allows a user to authorize dedicated proxies upload the cloud server her behalf, e.g., company may some employees files company's account...
With the rapid development of cloud computing, an increasing number individuals and organizations are sharing data in public cloud. To protect privacy stored cloud, a owner usually encrypts his such way that certain designated users can decrypt data. This raises serious problem when encrypted needs to be shared more people beyond those initially by owner. address this problem, we introduce formalize identity-based encryption transformation (IBET) model seamlessly integrating two...
With the establishment of intelligent transportation system (ITS), vehicular ad hoc networks (VANETs) play a significant role for improving traffic safety and efficiency. In order to avoid malicious attack resource abuse in VANETs, use digital signature scheme is widely regarded as first line defense achieve secure VANETs system. However, it still challenging task design conditional privacy preserving authentication scheme, resolve security privacy-preserving problems improve utilization...
Currently, the commercial separator (Celgard2500) of lithium-ion batteries (LIBs) suffers from poor electrolyte affinity, mechanical property and thermal stability, which seriously affect electrochemical performances safety LIBs. Here, composite separators named PVDF-HFP/TiN for high-safety LIBs are synthesized. The integration PVDF-HFP TiN forms porous structure with a uniform rich organic framework. significantly improves adsorption between electrolyte, causing higher absorption rate...
N/O/S co-regulates the surface trapping force of carbons, enabling fast and stable Na/K storage by adsorption weak intercalation.
Smart grid can greatly improve the efficiency, reliability, and sustainability of traditional grids. In industrial smart grid, real-time user-side metering data may be frequently collected for monitoring controlling electricity consumption. However, procedure collection lead to sensitive information leakage. To address security issues in this article, we construct an efficient identity-based aggregation scheme supporting batch verification by collector service provider, respectively, which...
Due to the rapid development of demand response management and distributed energy resources, prosumers are becoming more proactive, which also promotes emergence peer-to-peer (P2P) trading mechanisms. However, we find that it is quite difficult simultaneously achieve high computational efficiency, decentralized operations solution optimality in a P2P mechanism, called "P2P trilemma". In this paper, first propose novel negotiation mechanism for can maximize social welfare manner respect...
Hard carbons have broad prospects of application in potassium-ion batteries (PIBs) and sodium-ion (SIBs).
Fivefold twins are extensively present in nanoparticles and nanowires, enhancing their performance physical, chemical, mechanical properties. However, a deep insight into the correlation between properties fivefold bulk nanograined materials is lacking due to synthesis difficulties. Here, fivefold-twinned Ni synthesized via electrodeposition. The nanograins typically feature decahedral icosahedral shapes similar particles. material exhibits yield strength of ≈1.7 GPa under both compression...
Abstract Traditional machine learning requires collecting data from participants for training, which may lead to malicious acquisition of privacy in participants’ data. Federated provides a method protect by transferring the training process centralized server terminal devices. However, still obtain through inference attacks and other methods. In addition, provided varies quality, excessive involvement low-quality can render model unusable, is an important issue current mainstream federated...
Provable data possession (PDP) allows a user to outsource with guarantee that the integrity can be efficiently verified. Existing publicly verifiable PDP schemes require perform expensive computations, such as modular exponentiations for processing before outsourcing storage server, which is not desirable weak users limited computation resources. In this paper, we introduce and formalize an online/offline (OOPDP) model, divides procedure into offline online phases. OOPDP, most of...
A vehicular ad hoc network (VANET) is a special mobile that provides vehicle collaborative security applications using intervehicle communication technology. The method enables vehicles to exchange information (e.g., emergency brake). In VANET, there are many platoon driving scenes, where with identical attributes (location, organization, etc.) organized as group. However, this organization causes the issue of threats (message confidentiality, identity privacy, because an unsafe wireless...
Vehicle ad-hoc networks (VANETs) can offer numerous benefits, but also face many privacy and security issues. There exist the certificate management burden key escrow issue in traditional public infrastructure (PKI)-based identity (ID)-based privacy-preserving authentication schemes, respectively. In addition, of some existing cryptographic schemes depends on strong assumptions about ideal tamper-proof devices. To address these issues, a certificateless aggregate signature (CLAS) scheme for...

As the next-generation grid, smart grid (SG) can significantly enhance reliability, flexibility as well efficiency of electricity services. To address latency and bandwidth issues during data analysis, there have been attempts to introduce fog computing (FC) in SG. However, computing-based (FCSG) face serious challenges security privacy. In this paper, we propose a privacy-preserving aggregation scheme that supports dynamic billing arbitration, named PPDB. Specifically, design four-layer...
