Hybrid information security system via combination of compression, cryptography, and image steganography

Abstract

<span lang="EN-US">Today, the world is experiencing a new paradigm characterized by dynamism and rapid change due to revolutions that have gone through information and digital communication technologies, this raised many security and capacity concerns about information security transmitted via the Internet network. Cryptography and steganography are two of the most extensively that are used to ensure information security. Those techniques alone are not suitable for high security of information, so in this paper, we proposed a new system was proposed of hiding information within the image to optimize security and capacity. This system provides a sequence of steps by compressing the secret image using discrete wavelet transform (DWT) algorithm, then using the advanced encryption standard (AES) algorithm for encryption compressed data. The least significant bit (LSB) technique has been applied to hide the encrypted data. The results show that the proposed system is able to optimize the stego-image quality (PSNR value of 47.8 dB) and structural similarity index (SSIM value of 0.92). In addition, the results of the experiment proved that the combination of techniques maintains stego-image quality by 68%, improves system performance by 44%, and increases the size of secret data compared to using each technique alone. This study may contribute to solving the problem of the security and capacity of information when sent over the internet.</span>

Implementing and developing multi-stage cryptography technique for low-cost long-range communication system

“…It is essential to understand the two primary types of cryptographic keys: symmetric keys and asymmetric keys [16]- [20]. Symmetric key encryption involves generating one private key, which is then shared between two authorized individuals.…”

“…Without the private key, no one else can view the message's content. Using the same private key, the intended recipient can decrypt the message and restore it to its original format [16], [18], [20]- [24]. Examples of symmetric keys include advanced encryption standards (AES), blowfish (BF), and data encryption standards (DES).…”

“…We propose a new encryption system that utilizes one or more symmetrical encryption techniques to modify characters, numbers, and symbols and encrypt plaintext with a private key. Our system incorporates the encryption methods outlined in references [16], [18], [20]- [22] to enhance security. We aim to provide a more robust and effective method of data encryption that can be applied in various settings to ensure the protection of sensitive information.…”

Development Paillier's library of fully homomorphic encryption

“…This innovation addresses a fundamental challenge in cryptography: ensuring the secure generation, storage, and distribution of shared session keys. This progress significantly bolsters data security, enabling servers to receive encrypted data, process it, and return encrypted results, all while maintaining open data and encryption keys within a secure segment during network interactions [5]- [8]. For instance, consider a scenario where a hospital holds a substantial amount of private and sensitive patient information; it can homomorphically encrypt the data and transmit it to a third party for analysis.…”

A survey on Rijndael based LSB Audio Steganography techniques

“…The security and capacity issue might be resolved in part thanks to this study. [14], [15][16] , [17], We've seen that error-correcting codes and steganographic methods have a close relationship. He introduced a new steganography that combines LSB and a new error-correcting code with Rijndael phonetic steganography.…”
