The smart city environment includes dozens or even hundreds of various services in various areas of interest to users and aimed at improving the standard of living. These include services related to very sensitive aspects such as health, education, banking, and services that have a secret aspect. Cloud service providers need user data in order to be able to authenticate him in order to be able to access and access the desired service. Therefore, confidentiality, privacy and security are essential conditions for this type of communication. This type of complex and intrusive services leads to the need to provide effective solutions and mechanisms for authentication processes based on digital identity information. The process of building and managing trust between service providers and users needs a system of standards, so this paper provides a framework based on the archived behavior of users and cloud service providers operating within the approved trust circle in a smart environment based on the blockchain and its advantages in reliability, transparency and decentralization, while providing a mathematical model for evaluating and calculating trust standards for all subscribers as a basis for completing the authentication process and accessing services. © 2023 IEEE.

Centralized systems that require third parties remain opaque and represent a single point of failure. Therefore, in accordance with the requirements of cloud services and identity management mechanisms, it is necessary to move towards more transparent and collaborative methods. That is, all service providers under the same federation deal positively with the issued identity of the user. The distributed format gives good potential for ID management systems and treats everyone with the same level of validity. This paper presents a blockchain-based identity management system for the purpose of creating a federated identity management system that is used by multiple organizations by Taking advantage of decentralization and high transparency in the blockchain. Several vital advantages of blockchain are positive for forming identity management systems characterized by transparency and high security, and privacy. Implementing the proposed system on a private Hyperledger Fabric blockchain network proved effective according to the criteria studied, and there is also great potential for improvement. The practical application of the proposed system proved high quality and promising possibilities in blockchain based identity management. © 2023 IEEE.

Typically, in the smart city concept, a wireless sensor network contains many power-constrained sensors. The sensors sensed data from the environment and transmitted them towards the base station in a cooperative way. Therefore, an efficient energy consumption strategy leads to extend the lifetime of wireless sensor networks. Furthermore, the clustering structure pattern regulates the data transmission and reduces the total consumed energy. In this paper, we propose a new routing protocol that represents an improvement on Energy Efficient Sleep Awake Aware Sensor Network Routing Protocol (EESAA) called Improved -EESAA (I-EESAA) for heterogeneous wireless sensor networks (WSNs). I-EESAA protocol consists of many algorithms for clustering, cluster head selection, grouping, sensor mode scheduling, and data transmission. The main idea of I-EESAA is the grouping concept that aims to form groups of sensors with the same application type and located in the same communication range. After groups forming, one sensor in each group will still be in active mode while the others enter sleep mode. Simulation results show that the I-EESAA protocol performs better than the DEEC, DEV-DEEC, and EESAA in network lifetime, the first node dies, cluster head selection process, and throughput. Three system models are present to test I-EESAA with different environments. © 2021 IEEE.

In this paper, a distributed model predictive control architecture based on graph theory for integrated large-scale nonlinear process systems is proposed. This architecture is first agglomerated using popular community detection techniques and then organized on account of the relative master–slave relationship according to the ample information of interactions among separate subsystems. Both sequential and iterative distributed nonlinear model predictive coordination forms are considered for the reduction of the communication and computational burden within an acceptable loss of performance. Furthermore, the control performance of the large-scale integrated system could be improved to some extent under the architecture and the communication strategy we propose, whereby a brave exploration is made on the relationship between the control structure and the control performance, ulteriorly obtaining some notable results towards the untapped territory. The effectiveness of the proposed coordination method is evaluated by a standard reactor-separator process system.

Enterprise-focused blockchain applications that offer safe, anonymous, and immutable transactions are growing as blockchain technology matures. Traditional blockchain architecture has low performance and scalability, making it unsuitable for enterpriselevel applications with high concurrency and massive data. This paper studies and proposes a simplified Byzantine fault-tolerant (SBFT) consensus algorithm to improve consensus stage efficiency, a Task parallel smart contract model to maximise multi-core system parallel efficiency, and an improved blockchain system architecture to reflect the lightweight, low coupling nature of blockchain technology. It facilitates corporate application secondary development and the ParaChain blockchain and smart contract technology. Experimental verification compares the parallelization - based ParaChain blockchain’s TPS and scalability. PBFT-based blockchain systems have been greatly improved. © 2024 The Author(s).

One of the most critical problems facing the blockchain technology industry right now is how to protect the privacy of users’ data on the blockchain in a way that is both effective and cheap. Based on the Pedersen commitment and the Schnorr protocol, this study comes up with a secure multi-party computing protocol (BPLSM). By making the structure of the protocol and doing formal proof calculations, it has been shown that the protocol can be used in the blockchain network to combine private messages for efficient signing while keeping people’s identities secret. Furthermore, by looking at the nature and security of the protocol, it is also possible to find that the BPLSM protocol on the blockchain has a low cost of computing and a high level of information secrecy. Furthermore, it was found that the BPLSM protocol takes less time to check than the current mainstream BLS signature in a simple multi-party transaction with a fixed number of participants. © 2024 The Author(s).

Many multi-dimensional (M-D) graph signals appear in the real world, such as digital images, sensor network measurements and temperature records from weather observation stations. It is a key challenge to design a transform method for processing these graph M-D signals in the linear canonical transform domain. This paper proposes the two-dimensional graph linear canonical transform based on the central discrete dilated Hermite function (2-D CDDHFs-GLCT) and the two-dimensional graph linear canonical transform based on chirp multiplication-chirp convolution-chirp multiplication decomposition (2-D CM-CC-CM-GLCT). Then, extending 2-D CDDHFs-GLCT and 2-D CM-CC-CM-GLCT to M-D CDDHFs-GLCT and M-D CM-CC-CM-GLCT. In terms of the computational complexity, additivity and reversibility, M-D CDDHFs-GLCT and M-D CM-CC-CM-GLCT are compared. Theoretical analysis shows that the computational complexity of M-D CM-CC-CM-GLCT algorithm is obviously reduced. Simulation results indicate that M-D CM-CC-CM-GLCT achieves comparable additivity to M-D CDDHFs-GLCT, while M-D CM-CC-CM-GLCT exhibits better reversibility. Finally, M-D GLCT is applied to data compression to show its application advantages. The experimental results reflect the superiority of M-D GLCT in the algorithm design and implementation of data compression. Copyright © 2024, The Authors. All rights reserved.
