Q1. The following key information and right hand side R11 are input into the DES round function F in the twelfth round of the algorithm.
C11 = 11001100 00001111 11000000 1111, D11 = 11100000 00001111 11000000 0011
R11 = 01000111 00110011 00110011 00011100. Use this to calculate K12 and the result of the function F(R11, K12).
Q2. 2. In AES, suppose the keys W(4), W(5), W(6) and W(7) are as follows:
W(4) = W(6):
01100010
01100011
01100011
01100011
W(5) = W(7):
01100010
01100011
01100011
01100011
Find W(8).
