Privacy plays a central role in many application domains that utilize blockchain technology. It is central in Personal Data Management, Electronic Health records, or systems that interact with any public institution. However, blockchains are subject to ...

Token-based authentication is usually applied to enable single-sign-on on the web. In current authentication schemes, users are required to interact with identity providers securely to set up authentication data during a registration phase and receive a ...

Ethereum is the typical representative of the second generation of Blockchain technology. To achieve anonymity and decentralization, Ethereum utilizes a structured P2P network for data broadcasting, replication, and synchronization. The Ethereum P2P ...

By rendering game scenes on the remote cloud and delivering real-time video to end devices via the Internet, cloud gaming enables players to access game services anytime anywhere despite the hardware capacity of their terminals. However, as a commercial ...

With network slicing technology, 5G changes the classical mobile network business model from a network-operator-oriented business to a more open system with multiple stakeholders. In this context, a network slice broker plays the role of agency between ...

The adoption of industrial internet of things (IIoT) greatly improves the efficiency of industrial facilities by providing more accurate and rich information and increasing automation. The benefits are further amplified when IIoT is integrated with ...

This paper proposes a novel embedded Markovian queueing model of the M(1,n)/Mn/1 type in order to establish a theoretical foundation to design a blockchain-based system with specific interest in Ethereum. The model assumes variable bulk arrivals of ...

After the outbreak of the new coronavirus pneumonia, it has been broadcasting soon. Medical supplies are out of used. Chinese people have provided medical supplies and raised donations to help Hubei Province, China. While, Red Cross Society of Hubei ...

Online social networks have become very important sources of personal data that contain preferences, tastes, interests and friendships of their users. The potential that these data may be exploited poses a rising concern over how privacy is protected by ...

Data sharing is a vital method for data intensive and cooperative work-based applications. A central database system, which collects and stores data generated from different parties and provides open access, can not only save costs on infrastructures, ...

With the rapid growth of mobile network and infrastructures, location-related services accross multiple domains have received a great deal of attention. However, privacy is always an important problem that has a great influence on services. In order to ...

Package managers have become essential for software distribution and management. Their goal is to allow users to install programs, drivers, or updates in their systems in a secure, quick, and often, unattended way. However, in recent years, attackers ...

In recent years, edge computing transforms the network edge into an intelligent platform to provide better services for users by making storage, computing, control and network function closer to end-users, things, and sensors. However, due to the ...

The Ethereum cryptocurrency system becomes prevalent with the increasing number of daily transactions. It is a high-quality channel to secretly transfer information because senders and recipients are pseudonymous and transactions are tamper-resistant. ...

The slim chain is proposed in this paper in an effort to address and resolve the scalability issue of blockchain-based crypto computing by managing the volume of the blockchain itself. An adequate balancing of computation across on/off-chain is expected ...

With the exorbitant growth in the number of connected devices, the lack of proper identity and access management (IAM) mechanisms has become a major concern. The traditional IAM systems, which focus solely on managing people's digital identities, fail ...

A blockchain is a gradually increasing list of "blocks" containing information that are linked together using cryptographic hashes. It is a distributed, decentralized, and public digital ledger technology. Blockchains have caught not only the attention ...

Blockchain is a complex network structure, which has the properties of members and the network relationship of their transactions with each other. If we can quantify its network structure, it will be of great help to our subsequent work. Network ...

The hybrid chain is proposed in this paper to investigate on a new blockchain network that is to be built across private and main nets, namely, a hybrid chain. Note that the hybrid chain is distinguished from the on/off-balanced chain such that the ...

This paper proposes a fundamental theory to understand and explain blockchain based on dissipative structure theory and cognitive science. Propose that blockchain is a dissipative system that is an ordered state far from equilibrium, constantly ...

Blockchain Technology has been evolving from being a secure and immutable ledger of transactions for cryptocurrencies to a programmable interactive environment for building distributed reliable applications. This system proposes a secure platform to ...

Block chain is a revolutionary new technology proposed in recent years. It has the characteristics of decentralization, non-tampering with transactions, and extremely low transaction costs. These characteristics coincide with the decentralization and ...
