The conventional encryption methods are not appropriate for image cryptography as they contain large amount of data and the pixels have strong correlation. A new approach for chaotic encryption scheme for image is proposed through this paper. This image encryption algorithm is a modification of baptista's chaotic system. Analysis shows that the compression performance and encryption speed of the proposed system is much better.

image encryption has a significant role in the field of cryptography. A new encryption scheme is introduced to protect an image from unauthorized access, in this scheme two separate keys are used for image encryption and data hiding with high degree of security. The content owner encrypts the original uncompressed image using an encryption key. The least significant bits (LSBs) of the encrypted image are compressed using a data hiding key to create space to embed an additional data. Run-Length Coding (RLC) and Haar Wavelet compression technique is employed to reduce the image size and facilitate faster transmission. Encrypted and decrypted sections, the quality of image retrieval and data extraction are achieved from RLC with their respective keys. In this scheme user can extract an image, data and both image and data based on the keys used.

Medical imaging is an essential component of the healthcare sector, enabling the transfer of medical images between widely separated locations to improve healthcare business practices. However, the transmission of medical images across public networks can result in several security concerns, including those related to authentication, integrity, and confidentiality. Therefore, the major goal of this research is to ensure the security and accuracy of medical images by maintaining their confidentiality and integrity. This proposed method aims to enhance the security of medical images during their transmission across public networks. The method involves three main steps: compression, encryption, and embedding To achieve the goal of maintaining the integrity and confidentiality of medical images, this research utilizes a multi-step process. First, the medical image undergoes compression using the Singular Value Decomposition (SVD) technique to reduce its size and eliminate any noise. Following this, the compressed image is encrypted using the Advanced encryption Standard (AES) algorithm to ensure confidentiality. Finally, the encrypted image is securely enclosed within a cover image using the Least Significant Bit (LSB) steganographic technique to create a stego image. This technique ensures that the encrypted image is seamlessly incorporated within the cover image, without any visible or perceptible changes. This method ensures that the medical image remains confidential and maintains its integrity throughout the transmission process. Furthermore, this study developed the aforementioned technique, and the experimental outcomes were compared using MATLAB to hide medical images without encryption using LSB steganography as an additional layer of security. This study analyzed multiple medical image formats, including DICOM, TIFF, BMP, and JPEG. The findings indicate that combining encryption and steganography techniques provides improved results in terms of PSNR and MSE va

compression and encryption are two major aspects of cryptanalysis. compression reduces the large bandwidth requirement while encryption provides security against differential unethical attacks during transmission of images over a channel. The fractal based compression algorithm is proposed to remove the redundant data as it makes the image resolution independent. Here, AES and DES symmetrical encryption techniques are used over compressed images. The efficiency of proposed compression technique is evaluated by performance evaluation parameters like PSNR, MSE and SSIM. The effects on these performance evaluation parameters, when symmetrical encryption techniques are imposed on compressed images, are also analysed. The capacity of encryption techniques to procure the information from differential attacks is also analysed by calculation of differential parameters like NPCR and UACI. This experiment is performed on standard set of five grayscale test images. This paper shows that fractal-DES cryptanalysis system uses minimum bandwidth during transmission and provides better security and efficient reconstruction of images over fractal-AES cryptanalysis system.

Motion vectors signs encryption for H.264/AVC

Motion vectors signs encryption for H.264/AVC

Currently, research is focused on selective encryption to protect movies against attacks transmitted over a public network. This choice is taken to ensure the security of compressed data without adding an important supplemental computational time for the encryption. So the encryption module is inserted into the video compression chain. In this paper we present an encryption method based chaos inserted in the H.264/AVC chain specially for the motion vectors signs. The results will be deducted according to the values of PSNR (Peak Signal to Noise Ratio), SSIM (Structural SIMilarity) and the encryption rate. Motion vectors signs encryption (MVSE) seems being interesting to lose the visual quality of the video for Inter predicted frames since movies are sensible to the motion sign.

International conference & Expo on Emerging technologies for a Smarter World (CEWIT)

作者： Tao Xiang Chenyun Yu Jinyu Qu Xinwen Fu Department of Computer Science Chongqing University Chongqing China Department of Computer Science University of Massachusetts Lowell Lowell MA USA

Arithmetic coding is prevalent in compression for its remarkable performance, and it is also explored to design encryption schemes offering compression and secrecy simultaneously. Joint compression and encryption is a quite efficient and practical way to protect large volume of data, especially multimedia data, and numerous cryptosystem based on arithmetic coding have been proposed in recent years. In this paper, we present a new classification of secure arithmetic coding algorithms according to the selection of secret information. Then we analyze the security of encryption schemes based on interval swapping. We propose a simple yet efficient attack that could disclose the keystream that is used to make interval swapping decision. The attack works in static and content-based models of arithmetic coding.

Data must be compressed before being sent online, saving money and time. Encrypting the data and compressing it are also necessary to ensure secure and fast data transmission over the internet. This study presents an effective model based on chaos encryption using a piecewise logistic sine map, RC4 encryption, data compression, and LSB steganography. The results of the model are shown, along with a comparison with the other pre-existing models. The results of the proposed model are better than those of other pre-existing techniques in terms of various performance metrics, as discussed in the paper.

Elliptic Curve Cryptography (ECC) is a way to keep information secure. It is better than RSA because it can provide the same level of security with smaller codes. This causes less use of resources and lower memory needs. ECC surpasses RSA in several aspects, including lower bandwidth usage, faster computational times, and smaller key dimensions. Moreover, ECC can be effectively employed for image encryption. This paper explores the application of ECC in image encryption using MATLAB as the platform, delving into the processes of encryption, compression, and decryption.
