Paper consists of 3 sections:
section 1: (20 marks)
Q1: given 32 bit hex value, pass it through E/P table. E/P table was not given.
Q2: RSA algorithm. e = 7, p = 5, q = 11. Message in binary = (1000), find plain-text, cipher-text, d, z
Q3: Given 64 bit hex value, pass it through IP table, IP table was given.
section 2: (26 marks)
- configuration of pvlan with example.
- difference between MAC and one way. Hash value
- explain briefly working of ipsec AH and ESP in tunnel and transport mode. support AH in transport and tunnel mode.
- briefly explain the making of digital signature.
- differentiate the following.
- confusion and diffusion
- private key authority and private key certificate
- circuit level gateway and application level gateway firewall
(few more questions,,, i don't remember..)
