Towards securing Public-Key Storage using Hyperledger Fabric 4

Towards securing Public-Key Storage using Hyperledger Fabric

4th ieee international conference on Blockchain and Cryptocurrency (ieee ICBC)

When given a cryptographic public verification key, a receiver needs to be sure about the authenticity of the sender. Whenever an adversary is able to replace a wellintended public verification key of one of two participants within a communication relationship, she is able to send maliciously signed messages, using her own secret key, thereby compromising the whole authorization system. To overcome these issues for small to medium-sized distributed sensor networks, we previously proposed the NFC-Key Exchange protocol. Using the NFC-KE challenge-response authorization scheme, an attacker will not be able to intercept any communication unless she is authorized by a centrally trusted authority. though, the NFC-KE protocol considers only local file storages for the storing operations of the authorized public-keys. this approach is inherently vulnerable to any zero-day exploits that enable an attacker to infiltrate the filesystem. Additionally, once the central authority component is restarted or becomes corrupted, every previously exchanged key needs to be reauthenticated. By using the distributed Ledger Technology (DLT) framework Hyperledger Fabric, this paper proposes a new extension concept for the NFC-KE protocol in order to enhance the security of the public-key store. By using this extension, the NFC-KE protocol gains increased tamperresistance and outage resilience, due to the decentralized nature of the DLT.

In this paper, an energy-limited sensor schedule problem for remote estimation over a finite time horizon is considered in cyber-physical systems (CPSs). the sensor sends its local estimates to the remote estimator through a wireless network. At each time instant, the sensor decides whether it should send data or not so as to minimize the estimation error subject to limited communication resources. In this study, both the perfect communication channel and an unreliable channel are investigated. For the first situation, the optimal schedule scheme is presented as an explicit form. For the second one, an integer programming problem is formulated to get the optimal schedule sequence directly. At last, numerical examples are given to show the effectiveness of theoretical results.

Blockchain technology promises to overcome trust and privacy concerns inherent to centralized information sharing. However, current decentralized supply chain management systems do either not meet privacy and scalability requirements or require a trustworthy consortium, which is challenging for increasingly dynamic supply chains with constantly changing participants. In this paper, we propose CCChain, a scalable and privacy-aware supply chain management system that stores all information locally to give companies complete sovereignty over who accesses their data. Still, tamper protection of all data through a permissionless blockchain enables on-demand tracking and tracing of products as well as reliable information sharing while affording the detection of data inconsistencies. Our evaluation confirms that CCChain offers superior scalability in comparison to alternatives while also enabling near real-time tracking and tracing for many, less complex products.

the advent of Internet of things (IoT) has bring a new era in communication technology by expanding the current inter-networking services and enabling the machine-to-machine communication. IoT massive deployments will create the problem of optimal power allocation. the objective of the optimization problem is to obtain a feasible solution that minimizes the total power consumption of the WSN, when the error probability at the fusion center meets certain criteria. this work studies the optimization of a wireless sensor network (WNS) at higher dimensions by focusing to the power allocation of decentralized detection. More specifically, we apply and compare four algorithms designed to tackle Large scale global optimization (LSGO) problems. these are the memetic linear population size reduction and semi-parameter adaptation (MLSHADE-SPA), the contribution-based cooperative coevolution recursive differential grouping (CBCC-RDG3), the differential grouping with spectral clustering-differential evolution cooperative coevolution (DGSC-DECC), and the enhanced adaptive differential evolution (EADE). To the best of the authors knowledge, this is the first time that LSGO algorithms are applied to the optimal power allocation problem in IoT networks. We evaluate the algorithms performance in several different cases by applying them in cases with 300, 600 and 800 dimensions.

Aiming at the safety and efficiency problems in the whole life cycle management of aviation equipment, propose an efficient solution based on federated blockchain. Firstly, the data collected by the terminal sensing device is hash transformed through the blockchain system, and the initial data security is achieved by using the irreversibility principle of the hash algorithm while reducing the data volume of a single transaction in the block;secondly, the block is generated by the representative nodes elected through the Delegated-Proof of Stake (DPoS), and the consensus algorithm of the blockchain data verification adopts the delegated Byzantine Fault-Tolerance (DBFT) consensus algorithm to improve the consensus efficiency;finally, the transaction time curves are fitted and plotted according to the number of participating nodes, block size and network bandwidth in the simulation experiments to calculate the transaction efficiency under different situations. the experimental results show that the federated chain system is proved to achieve secure and efficient aviation equipment history storage and traceability. © 2022 ieee.

Wireless sensor network (WSN) is a network consist of multiple sensor nodes which sense and transmit data to a base station for data collection. Since the nodes in WSN are battery powered devices and nodes loss energy mostly due to transmission, an energy efficient routing protocol is needed to reduce the nodes energy consumption and prolong the network lifetime. However, existing routing protocols produce some drawbacks such as selection of cluster head with low residual energy and formation of different sizes of cluster which leads to uneven energy consumption among the nodes. therefore, an Ant Colony Optimization based Low Energy Adaptive Clustering Hierarchy (LEACH-ACO) protocol for energy efficient transmission in WSN is proposed in this paper. this research aims to develop a routing protocol that utilize the existing LEACH routing protocol to improve the performance of WSN and prolong the lifetime of the network. the results showed that LEACH-ACO protocol outperformed Direct Transmission (DT) and LEACH protocol in terms of network lifetime, energy consumption and energy per transmission. © 2022 ieee.

the technological development of the last few years has made a contribution to the form of the work. the tendency to development of work environmental with features that are like those in real life has gone mainstream. the COVID-19 World Pandemic increased the rapidity of implementing these new environmental policies in businesses. Moreover, globalization and sustainability principles allow businesses to be more intercultural and more responsible for the environment. the approach to creating remote work is 'it' thing in business now. there are enough researcher results that evaluate the impact of remote work on teamwork. they marked merits and demerits and lightened the main changes in competencies as a leader and a team member by offering some time management and psychological approaches for organization and supporting high productivity during work time. However, russian aggression Ukraine, which has been starting since 2014 and received the second active phase on February 24, 2022, influenced the remote work. the business routine got new challenges. this paper is the first step toward understanding how a war can influence a team member and how it can influence remote work: Ukraine case. the main research questions that were formulated for this research were: (1) how much influence the war has on remote work;(2) if there has been a change in the team development model;and (3) how much influence the war has had on leadership competencies. the research was based on literature reviews and the authors' own experience. © 2023 ieee.

Mobile Edge computing (MEC) has been envisioned as a promising distributed computing paradigm, where mobile users offload their tasks to edge nodes to decrease the cost of energy and computation. However, most existing works only consider the congestion of wireless channels as the crucial factor influencing the strategy-making process, and ignore the impact of the offloading among edge nodes. In addition, centralized task offloading strategies result in heavy computation complexity in center nodes. Along this line, we take both the congestion of wireless channels and the offloading among multiple edge nodes into consideration to enrich users' offloading strategies. To this end, we first formulate the offloading problem as a multi-user potential game, and then propose a distributed task offloading algorithm to reach an equilibrium state which can also protect individual privacy. Specifically, in the above task offloading algorithm, we propose two subalgorithms to select users for updating strategies: Parallel User Selection Algorithm (PUS) and Single User Selection Algorithm (SUS) in order to substantially accelerate the convergence. Extensive experiments on three real-world data sets validate that the proposed algorithm achieves a Nash equilibrium and effectively decreases the total user cost which is acceptable compared to the optimal solution.
