The process used in most block ciphers to increase their strength is
A.
Diffusion
B.
Confusion
C.
Step function
D.
SP-network
Explanation:
D: The SP-network is the process described by Claude Shannon used in most block ciphers to increase their strength. SP stands for substitution and permutation (transposition), and most block ciphers do a series of repeated substitutions and permutations to add confusion and diff usion to the encryption process.
