VBS_VPK_VR Method for DCI Cryptography
摘要
We will provide a streamlined, secure, and dependable technique for digital color image cryptography. The number of rounds in which this approach is implemented may vary; each round will make use of a unique private key and block size. The proposed method will make use of a complex private key (192 bits long each round), which will offer a large key space and be resistant to hacking efforts. The decrypted images that are produced will be heavily reliant on the values of the private key. The proposed method will not use any logical or arithmetic operations to encrypt-decrypt the colors values, these values will remain without changes, but they will be reordered. The recommended approach will employ a simple chaotic logistic map models to produce the required indices keys (one key for each round). Using the created indices key, a basic blocks reordering operation will be used to implement the encryption process, and a simple blocks reordering back operation will be used to implement the decryption process. The suggested approach will be adaptable; it can be easily and efficiently used to encrypt-decrypt small and big data. The suggested approach will be evaluated using different images, and the resulting experimental findings will be analyzed to demonstrate that the method meets the encryption-decryption quality standards. To demonstrate how the suggested approach shortens the encryption-decryption time, its effectiveness will be evaluated and its performance contrasted with that of other current approaches.
