Data sharding technology is a method of dividing complete data into several slices to protect its security during transmission and reorganization. In order to further ensure the security of data and improve the robustness of transmission, a data security transmission scheme based on sharding technology is proposed by combining error correction code technology. This scheme first segments the complete data and encodes it using Reed Solomon code. Then, the sliced data is encrypted using rsa public key cryptography algorithm. The target node decrypts the data using a private key and performs aggregation and summation. After decoding, the original data is restored. The experimental results show that this scheme can solve the problem of data transmission in which a small portion of data shards are lost or damaged due to poor network environment or attacks, fully restoring the original data, ensuring data security and transmission robustness, and reducing the impact of attacks or damages on data transmission. © 2023 IEEE.

Steganography deals with hiding information, which offers ultimate security in defense, profitable usages, thus sending the imperceptible information, will not be bare or distinguished by others. In this paper, a multidirectional PVD hiding scheme with rsa algorithm is proposed. Secret bits are embedded in three directions of a color image by dividing the non-overlapping blocks into R, G, b channels by selecting the minimum pixels of each block regrouping. In order to ensure the security of an stego-image, the work proposed by scheme is used, and in addition to that rsa algorithm is proposed.

In the recent era, the high speed networking technologies plays a vital role in Internet of Vehicles (IoV) is increasingly prevalent in numerous real-time applications. In IoV network, the communication between different vehicles are rapidly increased by sharing essential information such as traffic conditions, pathways, vehicle details, and position which enables to enhancing traffic safety and optimizing vehicle efficiency. The secure exchange of highly sensitive IoT network details among the vehicles is of paramount importance. Establishing robust security measures is essential to safeguard the integrity and confidentiality of this critical data exchange mechanism. The proposed model introduces a novel approach that leverages both steganography and encryption techniques to bolster the confidentiality and integrity of sensitive information exchanged among the vehicles in the IoV network. Initially, the sensitive information undergoes encryption using the Improved rsa (Irsa) algorithm. Subsequently, the data bits within the encrypted messages are subjected to binary flipping, and these altered bits are then embedded into a cover image using Pixel Value Differencing (PVD) and Pixel Value Indicator (PVI) steganography methods. This triple-layered security approach ensures the confidentiality and integrity of shared information in IoV, bolstering the security of sensitive messages and providing superior imperceptibility along with a high embedding capacity. The Experimental results shows that the proposed method produces an average PSNR of 41.5862 dB for 512x512 images and an embedding capacity of 1,028,455 bits, suitable for secret messages of 31,982 characters in size compare to the various existing methods.

In the digital transparent world, share the secret messages are challenged one. Visual cryptography (VC) is safer method for information transfer without any distraction by hackers. It is giving more security to the information sharing through digital form. This method hides the messages into images. So intruder cannot understand the distorted image and the data communication become secured. Through VC method number of shares has been generated from the original images. So here each RGB pixel shares are separately created by Visual Secret Share (VSS) scheme. The created multiple shares of the secret images are encrypted and decrypted with rsa algorithm. In the encryption process the multiplication technique is used for key generation process and public key is used for encryption process and private key is used for decryption process. Secret image's quality has been compared through the Peak Signal to Noise Ratio (PSNR) and Mean Square Error (MSE) values. The experimental result of decrypted image PSNR value is 156.32 and MSE value is 0.5031. The Number of Changing Pixel Rate (NPCR) and Unified Averaged Changed Intensity (UACI) values are compared for the secure level of the secret image. The result of decrypted image NPCR value is 69.44 and UACI value is 13.88. Finally, the experiment result shows that the proposed method is giving more security and quality of secret image sharing and also execution time is faster than existing method.

Panda and Chattopadhyay proposed “A Hybrid algorithm for rsa Cryptosystem” in 2017, they modified well-known algorithm rsa into modulo four prime numbers. Later, Gondaliya, Savani, Dhaduvai and Hossain proposed “Hybrid Security rsa algorithm in Application of Web Service” in 2018. However, we found that these two papers are highly similar, and the main focus of this article is how to determine the victim the (suffer) and the perpetrator (the plagiarist).

Image encryption is a crucial aspect that helps to maintain the images' confidentiality and security in diverse applications. Ongoing research is focused on improving the efficiency and effectiveness of encryption. Image encryption has many practical applications in today's digital world, such as securing confidential images transmitted over networks, protecting sensitive personal information stored in images, and ensuring the privacy of medical images. The suggested work represents a breakthrough in image encryption by proposing a model that leverages the power of DNA, rsa, and chaos. This model has three phases: key generation, confusion, and diffusion. The key generation phase employs a hash function and hyperchaotic technique to generate a strong key. During the confusion phase, the positions of pixels are rearranged, either at the image level or within blocks, using the Duffing chaotic map. Once the scrambling level is determined, each pixel undergoes two successive scrambling steps, with Henon and Arnold's chaotic map to change its location. During the diffusion phase, the encryption model employs a two- approach to ensure maximum security. Firstly, it utilizes dynamic DNA cryptography for non-adjacent bits, followed by robust rsa cryptography. The experimental results indicate that the model possesses a strong security level randomness and can withstand different attacks.

A highly secure communication method is essential for end users for the exchange of information which is not interpreted by an intruder. Cryptography plays a crucial role in the current and upcoming digital worlds, for secure data transmission in wired and wireless networks. Asymmetric and symmetric cryptographic algorithms encrypt data against vulnerable attacks and transfer to authenticated users. Steganography is a method for providing secure information with the help of a carrier file (text, video, audio, image, etc.). This paper proposes Deoxyribonucleic Acid (DNA)-based asymmetric algorithm which is used to encrypt the patient's secret information and its performance is compared with ElGamal, rsa and Diffie-Hellman (DH) cryptographic algorithms. The proposed asymmetric algorithm is applied to image steganography which is used for encrypting and concealing the patient's secret information in a cover image. The proposed method consumes less hardware resources with improved latency. Dynamic Partial Reconfiguration (DPR) allows to transform a selective area rather than complete shutdown of the entire system during bitstream configuration. Cryptosystem with DPR is designed, synthesized in Xilinx Vivado and simulated in Vivado simulator. The design is targeted at Basys3, Nexys4 DDR and Zync-7000 all-programmable SOC (AP SoC) architectures and programmed with secure partial bit files to avoid vulnerable attacks in the channel.
