Encryption and Decryption of Images based on Steganography and Cryptography Algorithms A New modelPrakash Kumar Sarangi
Encryption ensures that no matter how an attacker intercepts the image data, they are unable to decipher its contents without the decryption key. Compliance − Some industries or applications like healthcare or law enforcement have major image confidentiality and security requirements. image ...
SECURED ENCRYPTION AND DECRYPTION FOR IMAGE TRANSMISSION USING VISUAL CRYPTOGRAPHYWhen communication occurs through images, the images can either be confidential or not. But when we want to transmit an image that has to be known only to the sender and the receiver it becomes complicated. Because, ...
Furthermore, attempts to improve the security of public key cryptosystems to evade increasingly powerful attacks require increasing the bit length of the public and private keys, which significantly slows the encryption and decryption process. First-generation public key cryptosystems are built on the ...
Cryptography is the process of converting simple plain text into secret text called ciphertext, and converting ciphertext back to its original simple text, as shown in the Figure8-1. The process uses algorithms known as crypto-algorithms to perform the encryption and decryption process. ...
The above presentations all belong to symmetric encryption, in which the secret key works in both encryption and decryption processes. Whereas, asymmetric encryption uses two keys to boost security, i.e., the public key for encryption and the private key for decryption, eliminating the need to ...
The processes of encryption and decryption are involved in visual cryptography. A chromatic image is first broken down into three monochrome images with red, green, and blue tones during the encryption process. Next, the XOR method is applied to these three pictures to convert them into shares....
ICryptoTransform encryptor = aesAlg.CreateEncryptor(aesAlg.Key, aesAlg.IV); // Create the streams used for encryption. using (MemoryStream msEncrypt = new MemoryStream()) { using (CryptoStream csEncrypt = new CryptoStream(msEncrypt, encryptor, CryptoStreamMode.Write)) { using (Strea...
What is the concrete steps of SM2 encryption and decryption? Here are the steps specified inIPP Crypto developer reference: The standard operations of GFpEC functions are listed below: 1. Compute a shared secret Z of the private key U and a recipient public key W. 2. Derive a shared secre...
