Question

Q4: Choose the correct answer [2 marks]

a. In … cryptosystems, one algorithm is used for encryption and a related algorithm for decryption with a pair of keys, one for encryption and one for decryption (symmetric/asymmetric)

b. A … number generator uses a nondeterministic source to produce randomness (true random, pseudo random)

c. To ensure the … service, a server disconnects a client if he/she sends a large number of requests that exceeds the server’s threshold (access control/availability)

d. Eavesdropping is a type of … attacks (passive/active)

Answer 1

Since its a fill in the blanks with straightforward options, I shall simply give you the answers. If you need explanation as well, comment below and I shall provide.

(a) Asymmetric (In case of symmetric, only one key is used.)

(b) True random  (Pseudo random used modification of already used seed hence is not truly random)

(c) Acess control  (Availability is a utitlity used for info msg capturing)

(d) Passive (Since there is no direct access of data, the attacker passively access the data)
