Question 1
AES is a round cipher based on the Rijndal Algorithm that uses a 128-bit block of data. AES has three different configurations. ______ rounds with a key size of 128 bits, ______ rounds with a key size of 192 bits and ______ rounds with a key size of 256 bits.
Question 2
Check sum used along with each packet computes the sum of the data, where data is treated as a sequence of
Question 3
Using and in the RSA algorithm, what is the value of cipher text for a plain text if p=3, q=11, d=7, e=3, M=5, C=??
Question 4
How many distinct stages are there in DES algorithm which is parameterized by a 56-bit key?
Question 5
Using RSA algorithm, what is the value of cipher text C, if the plain text M = 5 and p = 3, q = 11 & d = 7?
Question 6

Question 8
Data Encryption Techniques are particularly used for ______.
Question 9
Usually information security in a network is achieved by:
Question 10
Find the correct choice:
Here A denotes sentence (Assertion) and R denotes reason for it.
A: We use IP address for network surfing that is for using internet instead of MAC address.
R: IP address is used to hide MAC address, which adds a security level from hackers and unauthorised people.
