Efficient Method to Message-Image Cryptography Using Reordered Image-Key
Color image may be secret or holding secret data, also secret messages may be so confidential. To protect these data, we have to use a simple and efficient method. In this research a method of data encryption-decryption will be presented. The suggested method will use a complicated PK to apply image encryption/decryption using XORing operation, the used image key will be reordered using a secret ordering sequence. Any modifications made to the PK during the decryption process will be regarded as a hacking attempt and result in corrupted decrypted data; hence, the encryption and decryption processes must employ the same secret information. The PK will provide an enormous key space that could resist any type of hacking attempts. The suggested method will be tested and the obtained results will be compared with those of DES and AES, the throughputs and speedup will be calculated. It will be shown how easily we can use encrypt decrypt color images with any size using a fix image key, and it will be shown how the suggested method maintain desirable values of MSE and PSNR parameters
