In order to deploy a secure WLAN mesh network,authentication of both users and APs is needed,and a secure authentication mechanism should be employed.However,some additional configurations of trusted third party agencies are still needed on-site to deploy a secure authentication system.This paper proposes a new block chain-based authentication protocol for WLAN mesh security access,to reduce the deployment costs and resolve the issues of requiring key delivery and central server during IEEE 802.11X authentication.This method takes the user’s authentication request as a transaction,considers all the authentication records in the mesh network as the public ledger and realizes the effective monitoring of the malicious attack.Finally,this paper analyzes the security of the protocol in detail,and proves that the new method can solve the dependence of the authentication node on PKI and CA.

The ultimate aim of a smart city is to enhance the quality of life for its residents and businesses through modern technologies in order to reduce resource deterioration and maintain overall costs. From this perspective, blockchain is one of these technologies that has received much attention during the recent years as it offers new alternatives for individuals and institutions in the smart city context. This study aims to explore the potential and contribution of blockchain in smart cities by studying and reviewing the literature of scientific research on the concept and fundamentals of blockchain, involving its most practical applications. In addition, it summarizes worldwide examples of success in using blockchain as well as exploring the challenges and opportunities related to this technology in smart cities. Thus, this study provides a useful reference for researchers to review all about the new blockchain technology.

The aim of this paper is to analyze the sharing and management of files in a tertiary institution using blockchain architecture. It is expected to enable an online system that could provide a decentralized architecture for multiple transfers and sharing of files amongst participants, to design a system that can provide data integrity and security of files using IBM Blockchain technology, to provide a system that can allow multiple user and multiple transactions at once. The research was motivated because of the security challenges associated with existing system which include: delay in transfer and sharing of files, much authority and task given to a single user in a centralized system, high risk of attack and loss of files, reduced speed of file transfer and file access/retrieval, limited number of users per time. Methodology adopted was Object Oriented Analysis Design Methodology (OOADM) in conjunction with Unified Modeling Language (UML) and IBM Blockchain Technology while the programming language used was HTML, CSS, Java and Node Js. The result after design was a decentralized cloud based file sharing and management system that enables multi-shared, replicated and permissioned transactions amongst participants in a network.

The world is changing exponentially-never before in the history of human kind have we experienced such change.There is an unprecedented opportunity to connect creatively disruptive innovations to transform the world for the better.One such creative disruption is blockchain technology.Blockchain is a decentralized distributed ledger,which is immutable and unhackable.In August 2016,the World Economic Forum released a report calling blockchain technology a 'mega-trend' that will shape society in the next decade,predicting that blockchains could store as much as 10% of global GDP by 2027 [1].
