Fantastic news! We've Found the answer you've been seeking!
Question:
'v'fith the ECB mode if there is an error in a block of the transmitted ciphertext only the corresponding plaintext block is affected. However, in the CBC mode. this error propagates Fo example an error in the transmitted Cl (Figure) obviously corrupts P1 and P21
Figure Cipher Block Chaining (CBC) Mode
a. Are any blocks beyond P2 affected'
b. Suppose that there is a bit error in the source version of P7. Through how many cipher text blocks is this error propagated" What is the effect at the receiver?
