摘要:This paper investigates the encryption efficiency of
RC6 block cipher application to digital images, providing a new
mathematical measure for encryption efficiency, which we will call
the encryption quality instead of visual inspection, The encryption
quality of RC6 block cipher is investigated among its several design
parameters such as word size, number of rounds, and secret key
length and the optimal choices for the best values of such design
parameters are given. Also, the security analysis of RC6 block cipher
for digital images is investigated from strict cryptographic viewpoint.
The security estimations of RC6 block cipher for digital images
against brute-force, statistical, and differential attacks are explored.
Experiments are made to test the security of RC6 block cipher for
digital images against all aforementioned types of attacks.
Experiments and results verify and prove that RC6 block cipher is
highly secure for real-time image encryption from cryptographic
viewpoint. Thorough experimental tests are carried out with detailed
analysis, demonstrating the high security of RC6 block cipher
algorithm. So, RC6 block cipher can be considered to be a real-time
secure symmetric encryption for digital imag
