Quiz for Cryptography for Network Security1. Which of the following is referred to as the ROT3 cipher?a. Split cipherb. Caesar cipherc. Diffuse cipherd. Block cipher2. Which of the following is referred to as C3 cipher?a. Block cipherb. Caesar cipherc. Diffuse cipherd. Split cipher3. How many possible keys exist in a 4-bit key space?a. 4b. 8c. 16d. 128To determine the number of keys in a key space, raise 2 to the power of the number of bits in the key space. In this example 2 4=164. Which of the following has the objective to find some weakness or insecurity in a cryptographic scheme?a. Abstractionb. Cryptanalysisc. Polymorphismd. Encapsulation5. Many cryptographic algorithms rely upon the difficulty of factoring the product of large prime numbers. What characteristic of this problem are they relying upon?a. It contains diffusion.b. It contains confusion.c. It is a one-way function.d. It complies with Kerchoffs principle.A one-way function is a mathematical operation that easily produces output values for each possible combination of inputs but makes it impossible to retrieve the input values.6. Dave is developing a key escrow system that requires multiple people to retrieve a key but does not depend upon every participant being present. What type of technique
