CBC and CTR (b) Suppose that there is a bit error in the source version of P1. Through how many ciphertext blocks is this error propagated? What is the effect at the receiver?

For simplicity, assume the encryption to be a simple XOR of the key with the plaintext. Let the encryption key be B4 (in Hexa).What is the entropy of a source which outputs, every second, one of 5 possible messages, α, β, γ, δ and κ with a probability of pα = 1/2, pβ = 1/4, pγ = 1/8, pδ = 1/16 and pκ = 1/16?

Give an example application where:The received information needs to be “exactly equal” to that transmitted. Discuss why that is?The message length in SHA-512 how many pages are occupied by a message of 2128 bits?In the Bernstein-Vazirani algorithm, suppose a = 1001. Analyze each step of the protocol and write down the overall state after each step to show explicitly how the algorithm works to find a.
