The following picture shows the i-th round of DES encryption and decryption. Assuming RD+1 and LD+1 are the same as LE+1 and RE+1, respectively, prove that the values of LE and RE on the encryption round are indeed the same as RD, and LD on the decryption round, respectively. Use the following values to verify your proof: LE = 04A7 and RE= DB6C. LE RE LE RE Encryption LD, LD RD, RD Decryption K
