In heterogeneous SDN networks, controllers deploying different protocols need to cooperate with each other and establish a global network view that can be passed to the network applications for unified management and end-to-end decision-making. Unfortunately, there is no standard northbound interface protocol to integrate heterogeneous SDN controllers. To address this issue in this paper, we propose an approach to find the mapping among controller ontologies in the SDN network with heterogeneous controllers in this paper. We regard these controller ontologies as a solution for discovering similar elements between local ontologies and global ontology. By mapping controller ontologies in the heterogeneous network together, we can form the complete network view to achieve centralized management. The idea behind the approach is to use ontology to represent the conceptual data of various heterogeneous controllers and then map similar semantic data together to form a consistent, global network knowledge. Evaluation results show that our approach has better accuracy than other algorithms and has an acceptable execution time. © 2021 IEEE.

Evaluating the adversarial robustness of deep networks to gradient-based attacks is challenging. While most attacks consider 2- and ∞-norm constraints to craft input perturbations, only a few investigate sparse 1- and 0-norm attacks. In particular, 0-norm attacks remain the least studied due to the inherent complexity of optimizing over a non-convex and non-differentiable constraint. However, evaluating adversarial robustness under these attacks could reveal weaknesses otherwise left untested with more conventional 2- and ∞-norm attacks. In this work, we propose a novel 0-norm attack, called σ-zero, which leverages a differentiable approximation of the 0 norm to facilitate gradient-based optimization, and an adaptive projection operator to dynamically adjust the trade-off between loss minimization and perturbation sparsity. Extensive evaluations using MNIST, CIFAR10, and ImageNet datasets, involving robust and non-robust models, show that σ-zero finds minimum 0-norm adversarial examples without requiring any time-consuming hyperparameter tuning, and that it outperforms all competing sparse attacks in terms of success rate, perturbation size, and efficiency.

In recent years, against the backdrop of smart grids, vehicle-to-grid (V2G) interaction has become a hot topic. With the increasing number of new energy vehicles, handling massive amounts of electricity transaction data has become an urgent problem in need of resolution. Ensuring the security of the vast quantities of electricity transaction data has emerged as a significant challenge. Therefore, two data aggregation schemes are proposed in this paper, both supporting batch verification and privacy protection in centralized and distributed scenarios, respectively. Firstly, an improved Paillier cryptosystem is utilized to achieve lightweight encryption in the proposed schemes. In addition, a novel distributed data aggregation structure that combines a large number of geographically distributed fog nodes with centralized cloud servers is introduced. This structure not only meets the requirements of lightweight encryption and resistance against single point failures but also reduces the communication complexity of distributed data aggregation to O(n). According to the security proofs and experimental analysis, it can be demonstrated that both proposed schemes are effective and secure, meeting the lightweight requirements of modern smart grid systems. © 2025 IEEE.

The Internet of Things (IoT) allows better solutions for managing challenges such as reliability and power quality in a smart grid environment. It also assists in adopting smart grid measures in smart city development. A smart meter in the smart grid environment must securely access services from a service provider via public channels. An adversary can pose several security vulnerabilities as the communication occurs through a public channel. Various researchers recently conducted several research types to determine the most challenging problems with the smart grid. The security features like integrity, authentication, and confidentiality are indispensable requirements of the smart grid environment. On the other hand, different objects like smart meters in the smart grid environment are resource-constrained, posing in designing lightweight security protocols. Hence, we propose a lightweight mutual authentication scheme to offer surveillance to smart meters in smart grid infrastructure. We analyze the suggested protocol against well-known security threats. Finally, we evaluate the performance of the protocol to illustrate its efficiency. © 2023 Elsevier Ltd

Data hiding in encrypted 3D mesh models has emerged as a promising crypto-space steganography technique. However, the existing methods have the potential to improve embedding capacity due to the underutilization of the model’s topological features. In this paper, we propose an innovative greedy selection and shortest diffusion strategy to select a proper reference set of vertices. Subsequently, the multi-MSB prediction and entropy coding are leveraged to further reduce the redundancy in the vertex coordinates for data embedding. By combining the new strategy and the efficient compressing of the embeddable vertices, we can raise the vertex utilization rate to approximately 90%. Experimental results show that our proposed scheme outperforms state-of-the-art methods, offering a substantial improvement in data payload for reversible data hiding in encrypted 3D models. © 2023, The Authors.

Identifying vulnerabilities in binary code with precision is a critical area of study in the field of software security. Most existing techniques fail to pinpoint the vulnerability's exact location, due to the extensive labelled data requirement and lack of targeted approach to improve on the problematic code. In this paper, we introduce VulPin, a system specifically designed to pinpoint vulnerabilities in binary code. This framework uses a hierarchical attention network that analyze program slices along with a vulnerability position matrix. Experimental outcomes indicate that our framework not only outperforms existing approaches but also pinpoints vulnerabilities more rapidly with a high Accuracy and a very low rate of false positives.

A low-cost high-speed radix-4 Montgomery modular multiplier without carry-propagate format conversion

engineering science and Technology, an International Journal 2024年 54卷

作者： Kuang, Shiann-Rong Wang, Chun-Yi Chen, Yen-Jui Department of Computer Science and Engineering National Sun Yat-sen University Kaohsiung 80424 Taiwan Information Security Research Center National Sun Yat-sen University Kaohsiung 80424 Taiwan

Modular multiplication is the most critical and time-consuming operation in numerous public-key cryptosystems used to establish secure networks. Especially in Internet of Things (IoT) applications, achieving low area complexity and high performance is crucial when designing modular multipliers. To meet these criteria, this paper proposes a low-cost, high-speed Montgomery modular multiplier that incorporates radix-4 Booth encoding and a simple two-level carry-save addition (CSA) architecture to reduce the execution time and area cost required to complete one modular multiplication. The proposed radix-4 multiplier operates on binary numbers as input/output operands and replaces the triple modulus with a negative value of the modulus, resulting in the minimum register requirement for modular multiplication. Furthermore, several simple circuits are designed to efficiently calculate the quotient and correction bits for negative multiples. Consequently, all the inputs required for the two-level CSA architecture can be generated on the fly, leading to a very short critical path delay. In contrast to previous designs that rely on additional carry-propagate adders to convert the modular multiplication result from carry-save form to binary representation, the proposed design reuses the two-level CSA architecture for format conversion. It also introduces a novel mechanism and a simplified zero detector to minimize the time and area overheads associated with format conversion. Theoretical analysis and FPGA implementation results demonstrate that the proposed radix-4 Montgomery multiplier achieves nearly the highest performance and the lowest area complexity when compared to existing radix-2 and radix-4 designs. As a result, it is highly suitable for deployment in IoT devices with limited resources. © 2024 Karabuk University

This paper proposes an enhanced resource selection (eInP-RS) scheme for efficient intra-platoon message delivery of cooperative awareness messages (CAMs) and decentralized environmental notification messages (DENMs). To achieve this goal, the eInP-RS scheme allows each vehicle to transmit CAM and DENM packets on a C-V2X channel (CH1) and an 802.11p channel (CH2), separately, and introduces four mechanisms to enhance the standardized sensing-based SPS scheme. A contention window (CW) size adjustment mechanism is introduced to enable a vehicle to adjust its CW size according to the information it collects on CH1 in order to avoid potential packet collisions on CH2; a resource partition mechanism is introduced to divide frequency-time resources in a selection window into two sets in order for vehicles moving in opposite directions to select different resources and thus avoid potential merging collisions on CH1; an intra-platoon cooperation mechanism is introduced to enable the PL of a platoon to know the resource and channel occupation information of the platoon's hidden nodes on CH1 and CH2; and a packet collision detection mechanism is used to enable a non-platoon vehicle to detect packet collisions occurring on both channels after a lane-changing maneuver to avoid potential merging collisions. Simulation results show that the proposed eInP-RS scheme outperforms the standardized sensing-based SPS scheme in terms of the intra-platoon CAM/DENM delivery ratio and the average intra-platoon DENM delivery delay.

The development of cloud services in recent years has mushroomed, for example, Google Drive, Amazon AWS, Microsoft Azure. Merchants can easily use cloud services to open their online shops in a few seconds. Users can easily and quickly connect to the cloud in their own portable devices, and access their personal information effortlessly. Because users store large amounts of data on third-party devices, ensuring data confidentiality, availability and integrity become especially important. Therefore, data protection in cloud storage is the key to the survival of the cloud industry. Fortunately, Proxy Re-Encryption schemes enable users to convert their ciphertext into other's ciphertext by using a re-encryption key. This method gracefully transforms the user's computational cost to the server. In addition, with C-PREs, users can apply their access control right on the encrypted data. Recently, we lowered the key storage cost of C-PREs to constant size and proposed the first Key-Aggregate Proxy Re-Encryption scheme. In this paper, we further prove that our scheme is a CCA-secure Key-Aggregate Proxy Re-Encryption scheme in the adaptive model without using random oracle. Moreover, we also implement and analyze the Key Aggregate PRE application in the real world scenario. © 2024, CC0.
