Suppose that one has designed a block cipher operation mode as C i = C i-1 XOR E K (P i ) P 0 =
Suppose that one has designed a block cipher operation mode as
Ci = Ci-1 XOR EK(Pi)
P0 = IV
a. Write the formula for decryption on the receiver side, and you also must illustrate encryption and decryption diagram for this scheme.
b. If an error happened to C3 during the transmission (all other blocks are transmitted correctly), which blocks of plaintext could not be recovered at the receiver? Please explain.
