Enhancing Data Security for Cloud Computing Applications through Distributed Blockchain-based SDN Architecture in IoT Networks
Blockchain (BC) and Software Defined Networking (SDN) are some of the most
prominent emerging technologies in recent research. These technologies provide
security, integrity, as well as confidentiality in their respective
applications. Cloud computing has also been a popular comprehensive technology
for several years. Confidential information is often shared with the cloud
infrastructure to give customers access to remote resources, such as
computation and storage operations. However, cloud computing also presents
substantial security threats, issues, and challenges. Therefore, to overcome
these difficulties, we propose integrating Blockchain and SDN in the cloud
computing platform. In this research, we introduce the architecture to better
secure clouds. Moreover, we leverage a distributed Blockchain approach to
convey security, confidentiality, privacy, integrity, adaptability, and
scalability in the proposed architecture. BC provides a distributed or
decentralized and efficient environment for users. Also, we present an SDN
approach to improving the reliability, stability, and load balancing
capabilities of the cloud infrastructure. Finally, we provide an experimental
evaluation of the performance of our SDN and BC-based implementation using
different parameters, also monitoring some attacks in the system and proving
its efficacy.Comment: 12 Pages 16 Figures 3 Table
Potent blockchain-rnabled socket RPC Internet of Healthcare Things (IoHT) framework for medical enterprises
Present-day intelligent healthcare applications offer digital healthcare services to users in a distributed manner. The Internet of Healthcare Things (IoHT) is the mechanism of the Internet of Things (IoT) found in different healthcare applications, with devices that are attached to external fog cloud networks. Using different mobile applications connecting to cloud computing, the applications of the IoHT are remote healthcare monitoring systems, high blood pressure monitoring, online medical counseling, and others. These applications are designed based on a client–server architecture based on various standards such as the common object request broker (CORBA), a service-oriented architecture (SOA), remote method invocation (RMI), and others. However, these applications do not directly support the many healthcare nodes and blockchain technology in the current standard. Thus, this study devises a potent blockchain-enabled socket RPC IoHT framework for medical enterprises (e.g., healthcare applications). The goal is to minimize service costs, blockchain security costs, and data storage costs in distributed mobile cloud networks. Simulation results show that the proposed blockchain-enabled socket RPC minimized the service cost by 40%, the blockchain cost by 49%, and the storage cost by 23% for healthcare applications
BlockChain: A distributed solution to automotive security and privacy
Interconnected smart vehicles offer a range of sophisticated services that
benefit the vehicle owners, transport authorities, car manufacturers and other
service providers. This potentially exposes smart vehicles to a range of
security and privacy threats such as location tracking or remote hijacking of
the vehicle. In this article, we argue that BlockChain (BC), a disruptive
technology that has found many applications from cryptocurrencies to smart
contracts, is a potential solution to these challenges. We propose a BC-based
architecture to protect the privacy of the users and to increase the security
of the vehicular ecosystem. Wireless remote software updates and other emerging
services such as dynamic vehicle insurance fees, are used to illustrate the
efficacy of the proposed security architecture. We also qualitatively argue the
resilience of the architecture against common security attacks
