• This paper addresses a list of existing research gaps involving the blockchain private permissioned consensus that require experts more consideration. • The focus of this paper is to propose a middleware lightweight PoET consensus of permissioned private blockchains for futuristic SMEs. • Smart contracts are created and deployed for the purpose to verify and validate requests of a new enterprise, participating in stakeholder transaction initiation lists, adding, and updating new transactional logs and deliverance records. A private permissioned chain is typically considered a fully protected authorized blockchain. The concept of a permissioned chain has become better single-entity control operation over the network and allows entry only to selected nodes, which most probably supports different small-medium enterprises and government officials. It is one of the prominent features of blockchain technology that maintains transaction integrity and security throughout the deliverance. This paper initially highlights the benefits of a permissioned private chain. Present the current issues of the Proof-of-Elapsed Time consensus mechanism for the distributed applicational environment. In order to make blockchain systems more adaptive for private chains, this paper proposes a middleware lightweight consensus based on PoET, named "B-LPoET". Objecting to being improved as a lightweight PoET from the predefined PoET in terms of verifying transactions and creating more blocks, to decide the mining right, and participants allows to acknowledge their identities before joining. The design of B-LPoET reduces the cost of multi-node efficiency by establishing a lightweight topology for selecting and waiting time of winning node using multithreading, which affects positively by increasing systems scalability. The experimental results of the B-LPoET illustrate that it performs better as compared with the existing PoET and other state-of-the-art consensus. [ABSTRACT FROM AUTHOR]

• This research emphasizes enhancing data security in real-time IoV communication considering secure communication also presents a trust-driven privacy method using encryption and steganography for IoV, "Efficient Algorithm for Secure Transmission (EAST)," integrating encryption and steganography algorithms. • We develop a data encryption method for IoV communication and verification using distinct symmetric encryption for all three components of vehicle communication. • Development of the standards on multiple systems for secure data transmission in IoV. Comprehensive performance measurement from various angles, including transaction cost, memory overhead, processing time, and energy use. • The proposed EAST method is compared with existing AES [12] , DES [13] , G-DES [14] , and standard LSB [15] using different indicators such as time efficiency, avalanche effect, PSNR, and file cover size. High-speed wireless network technologies play a vital role in autonomous vehicle communication systems (AVS), i.e., IoV (Internet of Vehicles), and enhance the effectiveness and reliability of the communication network. Since the size of IoV communication is rapidly growing, it is now an essential part of our regular routines. Due to its dynamic nature and massive size, it is essential to avoid any miss-communication and protect the data privacy of each vehicle.IoVallowsAVS to link remotely to each other and to various platforms and groups that may be using the same communications system. This quality link between vehicles and the need for information exchanges among vehicles introduces vulnerability and threats that can be exploited by cybercriminals. This research emphasizes on enhancing data security in real-time IoV communication. It presents a trust-driven privacy method using encryption and steganography for IoV. This method uses an Efficient Algorithm for Secure Transmission (EAST) that integrates encryption and steganography algorithms. The proposed EAST is then compared to the various current state of arts, i.e., AES (Advanced Encryption Standard), DES (Data Encryption Standard), G-DES (Generalized DES), and Standard LSB on the basis of various performance measuring parameters, i.e., encryption and decryption time, efficiency, avalanche effect, PSNR, and file cover size. Experimental results are promising for the proposed EAST method, which reported a better time efficiency of 0.86 ms, avalanche effect of 58.81%, and PSNR of 78.58%, compared to the current state arts.
