This paper presents a novel image encryption algorithm that leverages the chaotic properties of the Chen system, the cryptographic strength of OpenSSL, and the mathematical robustness of the Fibonacci Q-Matrix. The proposed method begins by generating an encryption key using the Chen chaotic system, known for its sensitivity to initial conditions and complex dynamic behavior. This key is then utilized in conjunction with a substitution box (S box) generated through OpenSSL to introduce non-linearity and diffusion into the encryption process. To further enhance security, the resulting image data undergoes a series of multiplications by a large number of Fibonacci Q-Matrices, exploiting their recursive properties for added complexity and confusion. Numerical results demonstrate the proposed algorithm's superior performance in terms of security and efficiency, making it a promising solution for safeguarding digital images against unauthorized access and cryptographic attacks. © 2024 Division of Signal Processing and Electronic Systems, Poznan University of Technology (DSPES PUT).

Due to today's constantly evolving online atmosphere the demand for security is at an all time high. Countless forms of media are being shared by users over the internet, with pictures being one such prevalent form. Users require robust forms of encryption when they send and receive images from their target parties. In this paper, a modified image encryption algorithm is discussed based on shuffling pixel arrangements in combination with modifying pixel values using bit-wise XOR. The encryption system is powered by the single switch jerk chaotic oscillator (SJCO) which produces three arrays of pseudo-random numbers based on the oscillator's initial conditions, The oscillator output is used to derive three keys, two shuffle keys and one key to carry out the XOR procedure. The paper also focuses on the implementation of the oscillator using hardware. The oscillator and XOR hardware modules utilized 178 and 5 logical units out of the available 56, 480. © 2024 IEEE.

Today encryption is a necessary step in the storage and transmission of information. Although very secure, well-known encryption algorithms are slow. Considering these aspects the aim of this work is to propose a secure and fast encryption algorithm based on chaotic maps. A random chaotic matrix is used and its key - the initial conditions, the control and scaling parameters - changes at each round. The number of rounds and an integer used for mixing lines and columns are also part of the key. © 2024 IEEE.

The proposed system presents an all-encompassing solution for embedding data within images, while simultaneously maintaining their visual quality. This is achieved through the utilization of the Reversible Data Hiding Algorithm (RRBE). Emphasizing both high data embedding rates and visual integrity, this system incorporates RSA encryption to guarantee data security. Additionally, the Least Significant Bit (LSB) technique is employed to minimize any noticeable distortions. This versatile and efficient approach caters to a broad spectrum of applications where secure and high-capacity data embedding within images is imperative. Consequently, it provides a robust solution to fulfill various data-hiding prerequisites. © 2024 IEEE.

This paper focuses on various encryption approaches to cope with different network attacks on IoT devices and a quality analysis of them has been performed. Currently network attacks such as, IoT botnets, DNS threats, shadow IoT, IoT body defense and IoT ransomware are the most vulnerable to IoT devices. These attacks can be solved using encryption algorithms such as Rivest-Shamir-Adleman (RSA) algorithm, Advanced encryption Standard (AES) algorithm, Data encryption Standard (DES) algorithm and Twofish algorithm. These algorithms are analysed using cryptography tools, which leads to increased performance of IoT devices. The performance of the proposed system is estimated using performance metrics such as time, encrypted data size and breakthrough time. From this paper it is observed that, AES consumes more operating time and more memory. DES and RSA consume average operating time while two fish consume less time. RSA uses less memory. The security level of AES, RSA and DES is lower than that of the two-fish algorithm because of the higher burst time. Security is provided by two fish algorithms better than other algorithms. © 2024 IEEE.

2024 Mid-term Symposium on Spatial Information to Empower the Metaverse

作者： Zhou, Qianwen Xiong, Ying Zhu, Changqing Ren, Na Nanjing Normal University Nanjing China Hunan Engineering Research Centre of Geographic Information Security and Application Changsha China

Selective encryption technology is a data security protection method that can balance encryption security and efficiency. Currently, there is ongoing research on applying this technology to vector geographic data. However, existing algorithms often use random selection methods for choosing objects to be encrypted, which results in lower security. To address this problem, we proposed a selective encryption algorithm for vector geographic data based on feature point grouping strategy. The study includes four steps: (1) Based on the user-input encryption ratio, calculate the feature point grouping thresholds for each element in the data. (2) Extract feature point sets for each element based on the grouping threshold. (3) Sort and group the feature point sets, reducing the smallest encryption unit to group objects within individual elements. (4) To reduce encryption costs and enhance the algorithm's resistance to attacks, perform frequency domain coefficient encryption and spatial domain coordinate value encryption in a stepwise manner on the group objects, ultimately producing the encryption results. The experiment showed that: (1) The decrypted encrypted data maintains consistency with the original data coordinates, achieving lossless decryption. (2) The correlation between encrypted data and the original data is significantly disrupted, resulting in a high level of randomness and thereby ensuring the algorithm's robust security. (3) The key space is substantial and highly sensitive, capable of withstanding brute force attacks. (4) The algorithm significantly improves encryption efficiency. (5) The algorithm displays resilience against deletion attacks and noise attacks. In conclusions, the proposed method enhances encryption efficiency while upholding a high level of security, thus it is an efficient selective encryption algorithm for vector geographic data. © Author(s) 2024.

In the field of cybersecurity, the need for reliable encryption algorithm is vast. Advanced encryption Standard (AES) stands as a widely utilized cryptographic algorithm for securing sensitive data. In today's world, AES is used for performing common packets encryption to bank webpage password encryption. The emergence of complex attacks creates challenges to the safety in using AES. The paper explores the combination of Padding Oracle Attack (POA) techniques and Gen AI methodologies to break AES encryption and predict passwords based on webpage contents. The proposed methodology explores around exploiting vulnerabilities inherent in the padding mechanism of AES. Using padding oracle, the attacker can find the length of the plaintext using the encrypted text. The paper aims to crack the underlying AES key by deducing the length of the encrypted password. Once the length is obtained, decryption and encryption processes are employed iteratively to reveal the AES key, subsequently enabling the extraction of the plaintext passwords. The paper aims to provide real-time evidence of the vulnerability of AES encryption, contributing to the enhancement of encryption standards as part of ethical hacking. The proposed approach is expected to demonstrate the feasibility of predicting passwords based on webpage contents, thereby highlighting the significance of reinforcing encryption protocols and understanding cybersecurity measures against evolving threats. © 2024 IEEE.

With the development and application of network technology, digital images, as a form of information transmission, are at high risk of being stolen or decrypted. Our scheme utilizes the nature of low dimensional chaos to generate a high dimensional chaotic system with more variables and higher complexity by mixing two different low dimensional chaotic systems to protect digital images and confirms that it outperforms the original system through simulation experiments. In this paper, a new image scrambling encryption algorithm for multi chaotic system is designed by combining improved tent mapping and high-dimensional chaotic system, and compared with the existing encryption scheme in terms of simulation experiments and security performance parameters, which proves that the scheme has better comprehensive ability. © 2023 IEEE.
