The design and development of secure nonlinear cryptographic Boolean function plays an unavoidable measure for modern information confidentiality schemes. This ensure the importance and applicability of nonlinear cryptographic Boolean functions. The current communication is about to suggest an innovative and energy efficient lightweight nonlinear multivalued cryptographic Boolean function of modern block ciphers. The proposed nonlinear confusion element is used in image encryption of secret images and information hiding techniques. We have suggested a robust LSB steganography structure for the secret hiding in the cover image.

Securing LSB steganography using bite substitution and image blocking

Protecting secret messages is a vital issue, in this paper’s research, a simplified, highly secure method of message steganography will be introduced. The proposed method will use a complicated PK, which contains information to select a secret block from the color image to be used as a covering block; also it will contain the values of the chaotic logistic map model to run this model to generate the indices key needed to substitute the message binary matrix. The PK will provide a huge keyspace capable to resist hacking attacks, the extracted message will be very sensitive to any minor changes in the PK, and any changes in this key during the extraction phase will be considered a hacking attempt by producing a damaged extracted message. It will be shown that the proposed method will be always efficient when changing the message length and changing the covering images. The proposed method will be implemented using various messages and various covering images, the obtained results will be analyzed using various types of data analysis methods to prove the improvements provided by the proposed method (quality, security, and efficiency).

The Design and Implementation of a Secure File Storage on the Cloud using Hybrid Cryptography

In recent years, cloud computing has become a popular way of storing and sharing data. However, security concerns have been raised about the safety of sensitive information stored on the cloud. Hybrid cryptography, which combines symmetric and asymmetric encryption, has been proposed as a solution to these concerns. This paper proposes a new hybrid cryptography approach for secure file storage on the cloud regardless of the type of deployment model i.e., either public cloud, private cloud, or hybrid cloud. The proposed approach uses a combination of the Advanced Encryption Standard (AES) algorithm, Triple Data Encryption Standard (DES) algorithm, and Rivest cipher 6 (RC6) algorithms are used to provide block-wise security to data. LSB steganography technique is introduced for key information security.

A Proposed Algorithm for Hiding a Text in an Image Using QR Code

In this paper, an algorithm to hide information in an image using QR code technology is presented. QR Code “QUICK RESPONSE CODE” is a two-dimensional array that can include different types of data and was first developed in 1993 for the Japanese Toyota Corporation for the purpose of tracking products through production and marketing. The researchers paid great attention to QR code technology especially in the field of information security. The proposed algorithm in this paper hides the secret text in the image in a random way by generating random positions and using the LSB “Least Significant Bit” method. After that, the random positions are saved in the QR code file, and this is the hiding stage. In the extraction stage, the QR code file is read first to extract the positions where the secret text has been hidden. After that, the secret text is read according to the LSB method. The algorithm was implemented using the C-Sharp programming language and Microsoft Visual Studio 2019 development environment. After conducting experiments on a number of images and extracting results based on the PSNR “Peak signal-to-noise ratio “test method, the results were good and the algorithm is very strong against a brute force attack. This algorithm can be used in building authentication systems. Index Terms— Information Security, Text Hiding, QR Code, LSB Steganography, Random Position, LSB.

Performance evaluation of LSB steganography based on multiple image formats

In the proposed research work steganography technique has been designed and developed for carrier images having different formats. The algorithm is applicable for the image formats: PNG (Portable Network Graphics), TIFF (Tagged Image File Format), JPEG (Joint Photograph Expert Group), and BMP (Bitmap). A single algorithm for almost all types of image formats provides many advantages. Depending upon the size of the secret message, network bandwidth, and allowable distortion we can choose the format of the carrier. For embedding secret messages, the LSB substitution technique is applied in this paper. We utilized the concept of imperceptibility by calculating PSNR (Peak Signal to Noise Ratio), MSE (Mean Square Error), SSIM (Structure Similarity Index Metrics), Histogram, and Entropy. The proposed work is analyzed for robustness with favorable results. Two steganalysis tools: Stegexpose and Stegdetect are used to detect the hidden secret message. For analyzing the complexity of work capacity, concealing and retrieval times are calculated. Furthermore, the comparative outcome for the proposed work is very promising for different carrier image formats.

Uzamsal Alanda Bir Kripto-Stegano Hibrit Uygulama

The need for data security in communication is increasing with the developing
 technology. The best way to ensure data security is cryptography. Humanity has
 proposed many cryptography methods for hundreds of years. Today, there are
 complex cryptography algorithms, which are quite secure but require high processing
 power. Cryptography techniques used in the past are less secure but require less
 processing power. This article proposes an extended version of the Vigenère cipher,
 which is an ancient encryption method. Extended Vigenère cipher is able to encrypt
 upper and lower case letters, numeric characters, and punctuation marks. In addition,
 the method can use upper and lower case letters, numeric characters and punctuation
 marks as encryption key, and there is no key length limit. The cipher text generated
 with the extended Vigenère cipher is also hidden in an image to keep it safe in the
 transmission medium. Hiding is performed with LSB steganography, which is
 another data security method. Thus, both the readability and detectability of
 confidential data are reduced. The cryptological security of the proposed method is
 measured by the Avalanche effect. Steganographic safety is evaluated with SSIM
 and PSNR measurements. A user graphical interface has been developed and the
 maximum payload of the carrier image is measured before encryption. Proposed
 method applied on some test images with different specifications. 1 bit key
 modification avalanche effect results of proposed method with random plain texts
 between 1000-10000 characters with a key length of 8 and 16 characters is close to
 50%. Also, SSIM value calculated over 0.99 each time while maximum
 steganographic payload of the test images reached.

Hybrid Cryptography: Secure File Storage on using AES, RC6 and Blow Fish Algorithm

In this era, cloud computing is used in various fields like industry, military, college, etc. for various services and storage of huge amount of data. Data stored in this cloud can be accessed or retrieved on the users request without direct access to the server computer. But the major concern regarding storage of data online that is on the cloud is the Security. This Security concern can be solved using various ways, the most commonly used techniques are cryptography and steganography. But sometimes a single technique or algorithm alone cannot provide high-level security. So we have introduces a new security mechanism that uses a combination of multiple cryptographic algorithms of symmetric key and steganography. In this proposed system, RC6 (Rivest Cipher 6), AES (Advanced Encryption Standard) and Blowfish algorithms are used to provide security to data. All the algorithms use 128-bit keys. LSB steganography technique is used to securely store the key information. Key information will contain the information regarding the encrypted part of the file, the algorithm and the key for the algorithm. File during encryption is split into three parts. These individual parts of the file will be encrypted using different encryption algorithm simultaneously with the help of multithreading technique. The key information is inserted into an image using the LSB technique. Our methodology guarantees better security and protection of customer data by storing encrypted data on a single cloud server, using AES, RC6 and Blowfish algorithm.

Information Hiding in Color Image Using Steganographic technique

Steganography is one of the important research subjects in the field of information security. It enables secret communication by embedding messages in the texts, images, audio, video files or other digital carriers. Among all the image information hiding methods, LSB embedding is widely used for its high hiding capacity and it is with great significance to detect the images with hidden messages produced by LSB embedding effectively, accurately and reliably. Therefore, many experts made efforts on the LSB steganography and steganalysis research over the years. This research presents a steganographic technique based on using LSB of one of the pixel color components in the image and changes them according to the message’s bits to hide. The rest of bits in the pixel color component selected are also changed in order get the nearest color to the original one in the scale of colors. This new method has been tested with others that work in the spatial domain through applying some common metrics which give us good result as a compared with the other steganographic tools.
