A Complex Matrix Private Key to Enhance the Security Level of Image Cryptography

Standard methods used in the encryption and decryption process are implemented to protect confidential data. These require many arithmetic logical operations that negatively affect performance of process. In addition, they use private keys a specific length, addition fixed length data block encryption, which may provide possibility penetration these methods, thus decreasing level security. this research paper, new method digital image cryptography is introduced. This based on using color as an image_key generate sophisticated matrix key (MPK) cannot be hacked. The proposed uses initial state set required parameters, with secret information needed key. data-block size variable, complicity MPK depends number selected rounds size. appropriate for publication Symmetry because it employs symmetrical complex encrypt decrypt images. simple yet very efficient terms throughput scalability. experiments show meets quality requirements can speed up encryption–decryption compared standard including DES, 3DES, AES, Blowfish.
