Q.4 Given the speed of current ordinary computer, estimate the amount of time necessary to crack a DES encryption by testing all 2 56 possible keys. Make a similar estimate for a 128-bit AES key. Use below instruction for this question. Go to web site https://www.cryptool.org/en/home and download CrypTool 1.4.31 Beta 06- English version Encrypt any text with DES-CBC with any key that you select go to analysis select symmetric encryption (modern) start the Brute Force analysis. What is the estimated time? Do the same things for AES algorithm. NOTE. Please watch DES and AES animation in this tool kit. (under Indiv. Procedures, select visualization of algorithms) Q.4 Given the speed of current ordinary computer, estimate the amount of time necessary to crack a DES encryption by testing all 2 56 possible keys.
