Group data sharing enables information sharing between multiple parties for cooperative purposes. However, the existing schemes only consider scenarios in which all parties in the same organization want to share data. Achieving secure data sharing between users of different groups is also a relevant research issue. In this paper, we propose a blockchain-based data sharing scheme for multiple groups with anonymity and traceability. Owing to the consortium blockchain technique, any user in the sys...

Abstract Three dimensional (3D) printed porous bioactive glass nanoparticles scaffolds (BGNS) exhibit excellent bone integration and bone regeneration capacities, but the early rapid ion release, brittle mechanical properties and lack of functions limit their application. In this work, photoluminescent biomimetic elastomeric BGNS were fabricated by directly assembling poly(citrate-siloxane) (PCS) on the surface of BGNS (BGNS@PCS). The morphologies, mechanical behavior, photoluminescent ability, ...

Abstract Previous solutions on security and privacy in Industrial Internet of Things (IIoT) focus primarily on the data or the deployment and communication problems of devices. However, the management and authentication of IoT devices for IIoT systems has received less attention. To facilitate the research on this area, we take the IIoT control system as an example. It is crucial to authenticate the relationships among devices to ensure that data can only be accessed by authenticated parties. In...

As one of the most important manners of personal and business communications, cloud emails have been widely employed due to its advantages of low-cost and convenience. However, with the occurrence of large-scale email leakage events and the revelation of long-term monitoring of personal communications, customers are increasingly worried about the security and privacy of their sensitive emails. In this paper, we first formalize a new cryptographic primitive named forward-secure puncturable identi...

Searchable Symmetric Encryption (SSE) allows a server to perform search directly over encrypted data outsourced by user. Recently, the primitive of forward secure SSE has attracted significant attention due to its favorable property for dynamic data searching. That is, it can prevent the linkability from newly update data to previously searched keyword. However, the server is assumed to be honest-but-curious in the existing work. How to achieve verifiable forward secure SSE in malicious server m...

Zero-knowledge sets (ZKS) is a basic cryptographic primitive that can be used to commit to a set S and prove statements such as $$x\in S$$ or $$x\notin S$$, without revealing anything else on S. Mercurial commitment is a useful tool to construct ZKS. Trapdoor q-mercurial commitment, an extension of normal mercurial commitment, results in more efficient ZKS with much shorter proofs when combining with a q-arity Merkle tree. ID-based trapdoor mercurial commitment is proposed by Chen et al. in 2011...

Abstract The emergence of the Internet of Things (IoT) has been greatly applied for improving people’s lives. Through the combination with cloud computing resources, the IoT is no longer constrained by computing and storage resources. For the storage service of IoT/cloud, it is crucial to keep the data within some specific geolocation borders for improving storage service quality. At the same time, it can protect the security of data against natural or man-made disasters. However, the outsourcin...

The notion of verifiable database (VDB) plays an important role in secure outsourcing of data storage, which allows a client, typically a resource-constraint one, to outsource the large-scale databases to an untrusted server and make retrieval and update queries. For each query request, the server responds with a query result and a proof which is used to verify the result. Plenty of research work has been done on designing efficient VDB schemes in the past years. However, it seems that all of th...

Abstract In the present study, a porous electrospun polycaprolactone (PCL) scaffold incorporated with bioactive glass (BG) particles was fabricated by combining phase separation with electrospinning. Chloroform (CF) and dimethyl formamide (DMF) were used as good solvents, while dimethyl sulfoxide (DMSO) was used as a poor solvent to generate pores on the fiber surface. The effects of PCL concentration, DMSO amount and BG particles dosage on the surface morphology of electrospun fibers were inves...
