Chapter 8, Problem 16RQ
Program Plan Intro
Cryptosystems:
It is a technique used to encrypt and decrypt data using keys. The user can send or receive data across insecure networks using this cryptosystems. This system may provide same or different keys for the sender and receiver.

Why is it important to study Feistel ciphers?arrow_forwardPart 1: Please answer the following questions about the fundamental of cryptography. Each question has only one correct answer. 1, Which description about block ciphers is NOT correct? Block ciphers encrypt the message block by block. A block cipher with a small block is vulnerable to the codebook attack. The encryption and decryption algorithms in block ciphers use the same secret key. The key length for block cipher should be very short to defend against the exhaustive key search attacks. 2, If the key length of a block cipher is 64 bits, what is the size of the key space? Hint: The key space consists of all possible keys. 64 264 232 2128 3, Modern block ciphers combine substitution S and permutation P operations to improve security. Based on the security rule, the cipher should not use consecutive substitutions or consecutive permutations.
