In light of the pervasive significance of privacy protection in contemporary society, the exploration of covert communication technology has been extensive, which is designed to safeguard communication behaviors and contents from disclosure. The decentralization, anonymity, and robustness of blockchain technology render it a more suitable medium for covert communication than traditional networks, which are vulnerable to tracing and destruction. Nevertheless, state-of-the-art blockchain-based covert communication schemes tend to focus on the concealment of a single type of constituent element in a blockchain transaction. These methods are able to resist detection methods for a particular element, yet are easily exposed under the joint detection of multiple classes of methods. The absence of resistance to joint detection methods targeting all elements presents a significant challenge that impedes the advancement of blockchain-based covert channels. Consequently, BlockWhisper is proposed as a blockchain-based hybrid covert channel that is capable of evading the recognition of various detection methods. Following the probability distribution model obtained from a blockchain transaction distribution analysis method, BlockWhisper is implemented using a top address list and a special hybrid coding method. The experiments demonstrated that Graph-based Detection (GD), Similarity-based Detection (SMD), Shape-based Detection (SPD), Entropy-based Detection (ETD), and Machine Learning-based Detection (MLD) yielded inferior results on this scheme, which substantiates the assertion that BlockWhisper possesses a strong ability to evade detection. Moreover, a comparison of BlockWhisper with other schemes reveals that it has a superior channel capacity on the basis of the guarantee of channel feasibility. © The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd. 2025.

All people on the planet expected agriculture to provide them with food to survive. The process of producing agricultural goods while integrating logistical elements is labor-intensive. Additionally, the lack of water exacerbated several issues with agricultural product production. The researchers did not adequately address the issues surrounding the lack of water over food chains. For supply chain management, this paper presented a novel deep learning based optimization mechanism to address the agricultural production challenges under water scarcity. Hence, this study proposed a Dynamic Salp Swarm Optimization (DSS) algorithm for feature selection. The DenseNet121 based Modified Runge–Kutta Optimization (MRKO) is used to predict the water usage. For supply chain optimization, unique technique called Beetle Swarm Optimization (BSO) proposed. In addition, this reduces production costs and time while increasing profitability. The Python simulator is used to perform simulations and implement the processes. According to the similar study, the proposed strategy outperforms all other methods in terms of supply chain manufacturing cost, time, accuracy, and recall for water consumption predictions. The overall sustainability enhanced and the agricultural supply chain water scarcity impact mitigated with these findings and it describes the potential of proposed work compared to state-of-art. From the comparative study, the proposed work demonstrated 96.81% accuracy, 95.7% precision and 96.8% recall with3.11% MSE, 2.10% MAE, and 3.10% RMSE results. © The Author(s), under exclusive licence to Shiraz University 2025.

Internet of Things (IoT) networks are expected to be a key enabler technology for smart cities, due to their ability to offer real-time monitoring. In this work, we propose a novel medium access control (MAC) protocol, inspired by the synergy of slotted ALOHA and hybrid automatic repeat request with code combining (HARQ-CC), termed as code combining slotted ALOHA (CCSA), to improve the performance of IoT networks with multiple randomly deployed sensors. Specifically, we provide analytical closed-form expressions for the network's outage probability as well as for its average throughput when CCSA is applied. Finally, we provide simulation results that reveal the authenticity of the derived expressions and reveal the capabilities of HARQ-CC to significantly improve the network's performance when the sensors' access is based on a random access scheme. © 2023 IEEE.

This article presents a background subtraction method to detect moving objects across a stationary camera view. A hybrid pixel representation is presented to minimize the effect of shadow illumination. A non-recursive background model is developed to address the problem with gradual illumination change. Modified Z-score labeling is employed to analyze the sample variation of the temporal sequence to build a multi-modal background. The same measure is further applied to detect the foreground pixels against the stationary background classes. Morphological filtering is employed to suppress the sensor noise as well as to fill the camouflage holes. A decision rule is formulated that considers the period of being stationary of a foreground object and the period of being absence of a background class to tackle the object relocation problem. The proposed approach along with nine other state-of-the-art methods are compared on various image sequences taken from the Wallflower and the I2R datasets in terms of recall, precision, figure of merit, and percentage of correct classification. The tabular results, as well as the obtained figures demonstrate the efficacy of the proposed scheme over its counterparts. © Springer-Verlag Berlin Heidelberg 2017.

Networks with wireless connection between nodes are far more convenient than a wired connection and are under rapid development. One major factor that ensures a truly significant network is the security features it possesses. In traditional communication, authentication mechanisms based on ECC were used to additionally augment the trustworthiness of data security over the network. In order to enhance security, the primary focus remained on growing the key size but, this brings in the intricacy to many internal load operations that are performed in latter stages and to the workload of calculations being performed. In addition, the speed of the cryptographic processes could not be compromised. Hence, to make the process smoother and reliable, our C2MAP protocol is introduced. Particularly, Chebyshev chaotic maps are applied to relate association indulging in the mechanisms involved that are required to perform mutual authentication. The proposed protocol is based on one of the properties of the Chebyshev polynomial, i.e., the semi-group property;which differs from other traditional security strategies, by those implementing complex hash functions and corresponding cryptographic algorithms. In order to compete with the existing ECC mechanism;parameters like throughput, end-to-end delay (E2D), and packet delivery ratio are taken into account;whose corresponding calculated scrutiny would prove that the enhanced security in authentication for communication protocol would be a better choice;by visualizing them through graphical presentations. © 2023, The Author(s), under exclusive license to Springer Nature Singapore Pte Ltd.

Different from traditional software, smart contracts operate on a world state and are driven by transactions. Therefore, classic fuzzing techniques cannot easily find the critical transaction chains in the above process. Specifically, we leverage static analysis to guide the fuzzing. We build a CFG based on smart contract bytecode and perform a symbolic execution to calculate the constraint conditions of critical paths. We also do data flow analysis on transaction dependencies. The former helps optimize the fuzz testing seed generation so that the testing space can be reduced. The latter assists the fuzz testing process in generating more targeted transaction chains that can trigger deeper vulnerabilities within the smart contract. We implement our approach in an efficient open-source fuzzer, "smartfuzz", which can discover vulnerabilities in industrial smart contracts when the original source code is unavailable. We evaluate smartfuzz with Oyente, one of the most widely-used smart contract vulnerability detector tools on two data sets of 546 total contracts. Results clearly indicate that smartfuzz is much more effective than the state-of-the-art tools and it also performs much better regarding code coverage.

Securing the uninterrupted data flow is crucial in the fast-advancing Internet of Things (IoT) market. This work investigates the incorporation of elliptic Galois cryptography and matrix XOR coding steganography to improve data security. The suggested solution employs the elliptic Galois cryptography protocol to encrypt sensitive data from diverse medical records. The private information is embedded within images through the matrix XOR encoding steganography algorithm. The Adaptive Firefly optimization approach is used to improve the efficiency of utilizing cover blocks for steganography. The effectiveness of the proposed technique is evaluated using various modern approaches. We analyze the efficiency and security of the proposed approach by comparing it with a previous hybrid method employing the New York State Department of Health dataset. The results unequivocally validate that our approach offers enhanced safety in Internet of Things (IoT) applications. © 2024 IEEE.
