What is the effect of a single-bit transmission error in the ciphertext when using the ECB and CBC modes of DES operation? More precisely, answer the following question: The plaintext blocks are {P1, P2, . . ., Pn). The ciphertext blocks are {C1, · · ·, Cn}. Suppose Ci contains a transmission error for some 1 <= i <= n. Which plaintext blocks will be recovered incorrectly?

Network transmission cabling

A network is a collection of devices connected by communication links. A device can be a computer or any instrument capable of sending and receiving data or information formed by other nodes toward the network. A channel that connects people or things is known as a network. It sends the data from one place to another. It is the basic concept of a computer, network, and data communications.

2. You have written a terminal emulation program which sends and receives individual 8-bit keystrokes. Now you want to add encryption, to provide confidentiality. You decide to make use of AES-256-CFB - that is AES with a 256-bit key, operating in cipher feedback mode. Once a connection is set up, assuming no padding, how many blocks will AES encrypt in order to transmit a line of 32 keystrokes?
