N blocks of plaintext (P1 to PN) are being encrypted in CFB mode into ciphertext (C1 to CN). Assume that two bits of C3 are erroneous (their binary values have flipped). What bits of C3, C4, and C20 are erroneous?
How do I solve the picture below?
Suppose a plaintext message x is encrypted using the Caesar cipher b = a +26 10 where each letter of the alphabet is assigned a numerical value (A = 0, B = 1, C = 2, ..., Z = 25), the variable a represents the numerical value of a letter in x, and b represents the numerical value of the corresponding letter in the ciphertext message y. If y = WKDR SC MYYV, then decrypt y to obtain the plaintext message x. Enter the decryption of each letter of y in the boxes below.

In the case of Public Key Authority It is necessary to make a request for B's public key, and the Public Key Authority must prepare a message (E(PRauth[PUB] || Request || Time1]) before sending it to A. What key A should use to decipher the message is up for debate.
