I know for image encryption, researchers generally discuss/report it's statistical attack analysis such as entropy and other security parameters but still an image encryption scheme can be break. Can someone suggest me all security parameters through which one can say that the proposed scheme is secure? I know, we can report correlation, NPCR, UACI and keyspace etc. But I am looking for some plaintext/ciphertext attack analysis and other parameters.
Hi Dr Jawad,
I think you may go through the following paper of Dr Fatih, He proposed check list to assure the security of an image encryption process.
Fatih Ozkaynak, Brief review on application of nonlinear dynamics in image encryption, Nonlinear Dynamics.

Image is another kind of data which can be hacked, but it can be secured with these parameters: encryption, impress hidden text, cut the images and make it assembly puzzle, crop few parts of image and replace with something else? May be this can help you:

There exist no test or analysis that can prove the perfection of encryption but the test of time. Researchers propose new techniques working on the weakness of previous approaches. Research in this area include breaking the previous algorithms or ciphers proposed. While there exist some standard test including entropy, correlation, histogram, key space, key sensitivity, noise analysis for robustness etc. But none guarantee that the scheme is unbreakable or secure but it is believed a secure algorithm should exhibit a certain behaviour in these tests.
Yes, there exist no perfect tests for analysis ciphertext, however, nist statistical tests for randomness is a good choice to prove the performance of good encryption.
nist is a good choice that you can use to measure the strength of your encryption approach it is reliable and widely used ,but it is still that there are no perfect or absolute test for encryption analysis also for image you should keep the featured as much as possible unchanged such as colored also histogram analysis should be considered to avoid hacking because histogram is used to discover any changes in the image you can add your contribution by increasing encryption and decryption times in compare with the previous approaches
Hello Mr. Jawad,
You can refer the given paper for statistical analysis tests for image encryption.
