<DIV> </DIV>
<DIV>Kindly clarify my doubt in Cryptography - practise test</DIV>
<DIV> </DIV>
<DIV>A symmetric algorithm must have certain characteristics to be considered strong.<BR>which of the followin is<FONT style="BACKGROUND-COLOR: #ffff00"> not</FONT> correct pertaining to these types of characeteristics?</DIV>
<DIV><BR>A. Confusion is carried out thru' transposition and diffusion is carried out thru diffusion.</DIV>
<DIV>B. Confusion is carried out thru substituition and diffusion is carried out thru transposition.</DIV>
<DIV>C. Confusion and diffusion are both used to increase the workfactor</DIV>
<DIV>D. The randomness of the key and functions in the algorithm correlate with the level of confusion and diffusion that is provided.</DIV>
<DIV><BR>I think the answer is A, but the practise exam says it is B</DIV>
<DIV> </DIV>
<DIV>Thanks & Regards,</DIV>
