The BGP router plays a crucial role in managing control and data planes, but this traditional approach hinders the exploitation of SDN advantages. Previous studies demonstrated the use of BGP for inter-domain and end-to-end communication. This paper advocates for the adoption of a fully SDN-based data plane packet switching strategy through the introduction of LPEES, a lightweight policy framework tailored for SDN-based inter-domain communication. LPEES strategically confines BGP's functionality to the control plane, preserving SDN benefits. Evaluation results confirm the effectiveness of LPEES compared to the BGP routing approach, as measured by throughput and various network quality of service (QoS) metrics. Additionally, LPEES streamlines inter-domain communication by utilizing a trust-based routing policy approach that can establish trust between communicating domains. The presented solution's main advantage is that it loosens the burden on the administrator by requiring less human interference to check the inter-domain communication security and privacy.

In order to overcome these limitations, this paper proposes an autonomous approach for firewall reconfiguration where all steps are automated, from the derivation of the security requirements coming from the logs of IDSs to the deployment of the automatically computed configurations. A core component of this process is React-VEREFOO, which models the firewall reconfiguration problem as a Maximum Satisfiability Modulo Theories problem, allowing the combination of full automation, formal verification, and optimization in a single technique.

For such systems, sensors are important to gather and process data as the lower level components. However, with the distributed deployment, decentralized systems are facing various security, privacy, and trust issues. For instance, any compromised sensor may leak sensitive data or be used to infect other entities within the system. It is also a long-term challenge to establish trust among different nodes and defeat malicious insiders. Here, there is a requirement to develop suitable management schemes for decentralized systems and networks regarding security, privacy, and trust. This special issue focuses on the identification of security, privacy, and trust issues in decentralized systems and the development of effective solutions in handling security, privacy, and trust issues for decentralized systems, for example, IoT, cyber-physical systems (CPS), smart city, and smart home.&lt;/p&gt;&lt;p&gt;In the first contribution entitled “A security-enhanced equipment predictive maintenance solution for the ETO manufacturing,” Cao et al. proposed a security-enhanced predictive maintenance scheme specifically designed for ETO-type production equipment. This scheme can use the industrial Internet of Things (IIoT) technology to monitor machines and equipment, constructing prediction models using machine learning methods and reinforcing the security of the prediction system through adoption of a decentralized architecture with blockchain distributed storage.

It heralds a novel paradigm in internet applications and societal engagement by weaving together diverse cutting-edge technologies to facilitate a virtual representation of the tangible world. Within the metaverse, the facets of economy, culture, and other dimensions are fully documentable, trackable, and quantifiable, largely owing to the capabilities of blockchain technology. Nonetheless, the transactional volume within the metaverse is typically substantial, posing challenges for a singular blockchain platform in terms of efficiency and support capacity. Consequently, a multi-blockchain infrastructure becomes essential to underpin the economic fabric of the metaverse. Enabling the collaborative operation of multiple blockchain platforms, specifically achieving the seamless transfer of value across different blockchain ecosystems, has emerged as a critical challenge. To address this challenge, this paper introduces a cross-chain protocol predicated on a multi-role notary system designed to facilitate inter-blockchain value transfers. The protocol specifies the functions of different entities within the notary framework, allocating specific duties to notaries, committees, and a leader. It also promotes mutual oversight among notaries to sustain a dynamic and equitable group structure. Furthermore, an incentive mechanism is proposed to motivate committee members toward prompt and judicious decision-making regarding votes.

Current cyberspace visualizations are overly complex and fail to accurately reflect node importance. To address the challenge of complex cyberspace visualization, this study introduces the integrated centrality metric (ICM) for constructing a metaphorical map that accurately reflects node importance. The ICM, a novel node centrality measure, demonstrates superior accuracy in identifying key nodes compared to degree centrality (DC), k-shell centrality (KC), and PageRank values. Through community partitioning and point-cluster feature generalization, we extract a network's hierarchical structure to intuitively represent its community and backbone topology, and we construct a metaphorical map that offers a clear visualization of cyberspace. Experiments were conducted on four original networks and their extracted backbone networks to identify core nodes. The Jaccard coefficient was calculated considering the results of the three aforementioned centrality measures, ICM, and the SIR model. The results indicate that ICM achieved the best performance in both the original networks and all extracted backbone networks. This demonstrates that ICM can more precisely evaluate node importance, thereby facilitating the construction of metaphorical maps. Moreover, the proposed metaphorical map is more convenient than traditional topological maps for quickly comprehending the complex characteristics of networks.</p>\u0000 </div>","PeriodicalId":14154,"journal":{"name":"International Journal of Network Management","volume":"34 6","pages":""},"PeriodicalIF":1.5,"publicationDate":"2024-10-07","publicationTypes":"Journal Article","fieldsOfStudy":null,"isOpenAccess":false,"openAccessPdf":"","citationCount":null,"resultStr":null,"platform":"Semanticscholar","paperid":"142641654","PeriodicalName":null,"FirstCategoryId":null,"ListUrlMain":null,"RegionNum":4,"RegionCategory":"计算机科学","ArticlePicture":[],"TitleCN":null,"AbstractTextCN":null,"PMCID":"","EPubDate":null,"PubModel":null,"JCR":null,"JCRName":null,"Score":null,"Total":0}

In recent years, vehicle data sharing is suffering to algorithm substitution attacks (ASA), which means backdoor adversaries can carry out filtering attacks through data sharing. Therefore, this paper designs a blockchain-based proxy re-encryption (PRE) scheme with cryptographic reverse firewall (BIBPR-CRF) for IoV. In our proposal, CRF can promise the internal safety of vehicle units. More specifically, it can prevent ASA attacks while ensuring chosen plaintext attack (CPA)-security. Meanwhile, the PRE algorithm can provide the confidential sharing and secure operation of data. Moreover, we use a consortium blockchain service center (CBSC) to store the first ciphertext and re-encrypt it with smart contracts on the blockchain, which can avoid single point of failure and achieve higher efficiency compared to proxy servers. Finally, we evaluate the performance of BIBPR-CRF with regard to communication cost, computational cost, and energy consumption.

The improvement lies in changing the mode of generating an update token, from the signer alone to the signer and the server cooperatively. Specifically, they first negotiate a secret value, which is then used by the signer to generate an update token. This mode ensures that only the entity who owns the secret value can use the update token to update a signature. Furthermore, we employ indistinguishability obfuscation to minimize information leakage through update token. These advancements make the improved updatable signature scheme achieve no-directional key update and unidirectional signature update.
