Hamming Distance (HD) is used as a security measure to evaluate some types of attacks on cryptosystems, I know that the good result o HD is 0.5? how is 0.51 better, worse or equivalent to 0.49? Is there any research study consider this evaluation process in details?
I think 0.51 has the same level of 0.49 in terms of security level
Thanks Dr.Mohammed, I agree with this answer, but I want detailed research with mathematical proves if it is possible
Please throw a glance at http://www.indjst.org/index.php/indjst/article/viewFile/50024/40739
Hamming distance is used in the design of encryption algorithm. For example, Maximum Distance Separable code or matrix is used in AES algorithm. This matrix provides maximum diffusion. Here, the larger the distance, higher is the diffusion.
The hamming distance of cipher text is very important with regard to the strength of the algorithm. The cipher text should exhibit the balance, i.e., the number of "1" bits should be equal to number of "0" bits. Any deviation is a bias and helps the adversary to decipher the cipher text.
Hi
Did you ever get your answer !?
Do you know any paper or article about your question!?
