Abstract: The latest 6G improvements secured autonomous driving's realism in Intelligent Autonomous Transport Systems (IATS). Despite the IATS's benefits, security remains a significant challenge. Blockchain technology has grown in popularity as a means of implementing safe, dependable, and decentralised independent IATS systems, allowing for more utilisation of legacy IATS infrastructures and resources, which is especially advantageous for crowdsourcing technologies. Blockchain technology can be used to address security concerns in the IATS and to aid in logistics development. In light of the inadequacy of reliance and inattention to rights created by centralised and conventional logistics systems, this paper discusses the creation of a blockchain-based IATS powered by deep learning for secure cargo and vehicle matching (BDL-IATS). The BDL-IATS approach utilises Ethereum as the primary blockchain for storing private data such as order and shipment details. Additionally, the deep belief network (DBN) model is used to select suitable vehicles and goods for transportation. Additionally, the chaotic krill herd technique is used to tune the DBN model’s hyperparameters. The performance of the BDL-IATS technique is validated, and the findings are inspected under a variety of conditions. The simulation findings indicated that the BDL-IATS strategy outperformed recent state-of-the-art approaches.

With the tremendous growth of modern communicating, sensing, computing, and analyzing devices and techniques, the last few years have witnessed industry growth and tremendous academic efforts in intelligent autonomous transportation systems (IATS) [1], imposes more convenient and safer transport facilities along with major impact on all the aspects of daily lives with smart vehicles and transport services. Due to the growing complexity, uncertainty, and diversity of strategies, behavior, and mechanisms included in the ecosystem, however, IATS currently have proved higher degree of social complexity rather than the expected intelligence, leaving several persistent problems that have not been resolved. One serious problem is the security risk caused by IATS evolving trends toward centralization [2]. The rapidly evolving technology includes cloud computing and Internet-of-Things (IoT) allow most of the information, decisions analyses and processed by cloud-based platforms or centralized authorities, that is considered as IATS’ “Achilles’ heel” and currently not available because of malicious attack, simply improper operations or performance limitations. Another problem is the lack of mutual trust amongst IATS entities [3]. Consequently, assets and money could not “flow” from one entity to other directly and smoothly without a trusted intermediary, which results in increased social complexity of IATS, hierarchical structures, and diversified mechanisms [4]. Fig. 1 demonstrates the structure of ITS.

The more commonly discussed topic interms of applications of the BT in transportation is logistics; indeed, several studies were introduced in the last few years. In a globalized world, many industries must design effective and longer supply chains to achieve success [5]. It implies that the difficulty of tracing and delivering goods should be fulfilled with a satisfactory informatics system. The blockchain serves various functions by protecting data and goods from malicious attacks in multiple agent supply chains [6]. Blockchain gives the opportunity of managing product storage quality at the time of guaranteeing and transportation the origin of product, thus creating trust between the suppliers. Many important issues can be resolved in supply chain management (SCM) by a blockchain, namely avoiding counterfeiting, flexibility, risk reduction, reports on stopped goods, speed of transfer, cost, and quality control [7].
Major enterprises, like Maersk and IBM, have built partnerships to examine blockchain implementation. Many stakeholders could depend on the blockchain to gain trust and to handle the fluctuation of data [8]. The supply chain and Traceability could be improved, adding values to the final products: all the transfers of goods could be validated and recorded by the consensus of each blockchain entity. The major challenges in supply chain BT application are to resolve the difficulty of ensuring that the physical layers (that is real goods) correspond to the digital layers (i.e., information that are stored) [9]. The usage of certified smart objects of IoT can brighten the future of this type of system. Several enterprises have invested in the supply chain application of BT, namely SKUchain, Provenance, Blockverify, and Jiocoin (launches its crypto-coin) that has created services to prevent forging of properties.
This article focuses on the design of blockchain with deep learning enabled IATS for secure cargo and vehicle matching (BDL-IATS). The BDL-IATS technique applies Ethereum as the fundamental blockchain for storing confidential data such as order details, cargo details, etc. Besides, the deep belief network (DBN) model is utilized to recommend vehicle and cargo matching during transportation. Moreover, the chaotic krill herd algorithm is applied for the hyperparameter tuning of the DBN model. The performance validation of the BDL-IATS technique takes place and the results are inspected under varying aspects.

During this method, a driving trajectory as well as natural driving data sets were utilized as network input to long-term memory network from the 5G enabled ITS: the probability matrix of all intentions are computed by softmax function. Afterward, the last intention probabilities are achieved by fusing the mean rule from the decision layer. Maskey et al.

This article has developed an effective BDL-IATS technique for secure cargo and vehicle matching in the IATS environment. The BDL-IATS technique has employed applies Ethereum as the fundamental blockchain for storing confidential data such as order details, cargo details, etc. Moreover, the CKHA with DBN model is utilized to recommend vehicle and cargo matching during transportation.
3.1 Design of IATS Based on DBN Model
Deep Belief Network (DBN) is a Deep Neural Network (DNN) collected of s several RBM and Back Propagation Neural Network (BPNN) stack [17] that utilizes an unsupervised greedy learning technique for adjusting the connection weight of all RBM layers and supervised learning manner for optimizing the network parameter. All RBM has of visible layer
where Vk and Hk stands for the binary state of every unit from kth visible as well as hidden layers. The lower energy function represents the most ideal state of networks, i.e., the lower forecast error to the EV charging voltage. With regularize and development of the energy function, the joint probability distribution of RBM is attained as:
where Z(θk) signifies the partition functions that implies the sum of every feasible state energy function of the group of Vk and Hk node from the normal charging voltage DBN technique, and is utilized as the main purpose of the optimized technique. Based on the structural features of RBM, the probability that ith units vi of visible layer Vk and jth unit hj of hidden layer Hk are activated are written as:
where σ(x) = 1/(1 + e−x) refers to the sigmoid activation functions.
The DBN trained technique to normal charge voltage has 2 phases of pre-trained and fine-tuned. During the pre-trained step, RBM1 obtains data on EV needed voltage, needed current, charging current, and temperature, and trained all RBMs from bottom-up order utilizing a layer-by-layer greedy learning technique for achieving the removal of high level feature of input data and the upgrade of connection weight of trained networks [18]. The resultant data is forecasted charging voltage. During the fine-tuned step, the BPNN gets the forecasted charging voltage as input and actually measured charge voltage as outcome, and always modifying and optimizing the network parameter from top to bottom from the method of supervised learning.
3.2 Hyperparameter Tuning of DBN Model
For tuning the hyperparameters of the DBN model, the CKHA is utilized and thereby optimized the overall performance of the network. KH is a novel generic stochastic optimized method to the global optimized issue. It can be simulated as performance of a krill swarm. Once the hunting to the food and communicate with everyone, the KH method repeat the execution of 3 actions and follows search way that progress the main function values [19]. The time relied place was mostly defined as 3 movements:
1. Foraging action;
2. The movement inclined by other krill;
3. Physical diffusion.
Even KH method adapts the Lagrangian method as demonstrated in the subsequent model:
where Ni, Fi and Di implies the foraging motions that are controlled by another krill and the physical diffusion of krill’s i correspondingly. A primary motion Fi cover 2 parts: the present food place and data on the preceding place. In order to krill i, it is express this motion as under:
where:
and Vf implies the foraging speed, wf represents the inertia weights of foraging motion from zero and one is the final foraging motion.
The direction managed by the secondary effort Ni, ai has been measured by 3 effects: target, local, and repulsive effects. To krill i, it could be expressed as under:
where N max stands for the maximal induced speeds, wn signifies the inertia weight of secondary motion from zero and one is the final motion controlled by other krill [20].
In order to the ith krill the physical diffusion was an arbitrary procedure. This motion contains 2 modules: a maximal diffusion speed as well as oriented vector. The look of physical diffusion is provided under:
where Dmax signifies the maximal diffusion speeds and δ refers to the oriented vector whose value was an arbitrary number amongst [−1, 1]. Based on the 3 above examined performances, the time-relied place in time t to t + Δt is expressed by the subsequent formula:
For enhancing search effectiveness and making sure convergence to an optimum solution, the chaos method was combined with KH structure to this study scope [21]. Assuming that Chebyshev map is one of the widely utilized chaotic behavioral maps, it can be feasible for generating chaotic orders quickly and effectually. Also, there is no requirement for retaining long orders. The Chebyshev map utilized under the CKH technique alteration the value of randomized parameters ωchebychev = (ωd, ωf) from KH.
The Chebyshev map upgrade parameters ωd and ωf as:
Eq. (12) takes a chaotic order in range of zero and one. To all independents implementation of Eq. (12),
During the case of CKH,
