Network Security

The word "network security" refers to a wide range of technology, devices, and processes. In its most basic form, it is a combination of rules and configurations that use both hardware and software technologies to safeguard the confidentiality, integrity, and accessibility of computer networks and data. Every company, regardless of sector, size or infrastructure, needs network security solutions to protect itself from the ever-increasing landscape of cyber threats that exist today.

Part 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. In the following combinations, which one violates the above security rule? ?1?1?2?2 B. ?1?1?2?2 C. ?1?1?2?2 4, Which…
