... This method can lead to inefficiencies when applied to images due to the large file sizes and high redundancy typically present in uncompressed image formats. These characteristics can result in increased encryption time and higher computational resources, which are not ideal for real-time applications like video streaming or live surveillance systems [16]. ...
... Firstly, images often contain a high degree of redundancy, with many areas of uniform color and intensity. Traditional block ciphers like AES and DES are designed for text data and may not efficiently handle the large data volumes and redundancy present in images, leading to inefficient encryption with possible performance bottlenecks [16]. Furthermore, the structure of image files might be altered in a way that makes them unusable or leads to significant quality degradation once decrypted, if standard encryption methods are used without modifications. ...

Long and short text messages are widely transmitted through various communication media, and some of these messages may be very secret or of a special nature, which requires protecting them from the danger of abusers, intruders, or data hackers. Given the importance of protecting text messages, a novel method will be presented focusing on simplifying the procedures to protect data and make the hacking process difficult.A high-level protection method will be provided using the complicated variable content private key; this key can be easily changed without changing the sequence of operations used in the encryption and decryption phases.A secret color image is to be used to generate the private key;both the sender and receiver must save this image, and the selected image key can be easily resized to get a key equal to the secret message length.To increase the degree of protection, it is recommended to divide the text message into blocks with a selected size, the sender and receiver must determine the size, and the byte in each block is to be combined into one vector. This vector will be rotated left using a specified number of bits determined by the sender and receiver.The proposed method will be implemented using various color images and text messages, and the results will be compared with other methods to prove the achievements obtained by the proposed method.

This study offers a new adjustment to the Advanced Encryption Standard (AES) in order to assure a high degree of security. This is achieved by replacing the binary (XOR) operation with a new (Xo) operation in each add-round-key stage. The Xo operation generated an extra six randomly selected control keys determined by six state tables (2, 4, 6, 8, 10, and 12) produced from the addition operation in the Galois Field GF (2^2 ,2^4 ,2^6 , 2^8, 2^10 and 2^12 ) in order to boost the algorithm's unpredictability. In the suggested method, an adversary requires at least probabilities of keys to break the message; hence, it improves the difficulty of the original AES against brute force attacks. also enhances the performance of additional security metrics, such as NIST tests, compared to the original AES. Consequently, this replacement, including the use of six keys in both the encryption and decryption processes, offers a new level of security and a higher degree of resistance to data breaches. The novelty of the proposed (Xo) technique lies in the construction of GF tables ( 2^6 , 2^10 and 2^12) to be used in the encryption and decryption process for the first time, as well as the approach utilized to create the code for it.

The security of private and sensitive data stored in the public domain is a major problem. It is critical for the user that data be safe both in transit and evenafter it has been stored on the server. The data owner must be guaranteed that the data held on the service provider site is safeguarded against data theft fromoutsiders, and the data must be protected even from the service providers. The secret key generation is one of the most important factors for the security ofany cryptographic system because the length of the key directly affects the performance and prevents various cryptographic attacks such as brute force attacks.At the application level, our developed system efficiently secures sensitive, private, and personally identifiable information by ensuring privacy andconfidentiality of data at rest in the public domain. This study also compares the performance of block cipher algorithms DES, 3DES, Blowfish, and AES. Itwas deduced from the result that AES consumes less time when compared to other symmetric algorithms with small consistent behavior for variouscryptographic operations with small, medium and big datasets..
