Modern ciphers can be categorized into two: symmetric ciphers and asymmetric ciphers. a) What are the limitations of symmetric ciphers, and explain each of them? b) There are two types of symmetric ciphers. List them and explain how they are different from each other in terms of the way they encrypt the message. c) Figure I below shows a round function in DES. Which part (L or R) has a better diffusion than which? Justify your answer. d) Based on your answer in (c), how to increase the diffusion level of this cipher? L-1 R-1 F R Ki
