Function Of Cryptographic Hashing And Masquerade Attack On Network

Question

1. Which of the following is NOT a function of cryptographic hashing:

a.    To provide the input to a signature algorithm
b.    To provide “shadow files” for critical security data such as passwords
c.    To compress data for efficient transmission
d.    To cryptographically bind parameters in a security protocol

2. A masquerade attack on a network involves:

a.    Discovering the pattern of traffic between two or more users
b.    Changing the contents of a message and sending it to an unsuspecting user
c.    Releasing the content of a message to users not holding the corresponding key
d.    Sending messages from fraudulent source

Summary

These multiple choice questions belong to Computer Science. The 1st question is about the function of cryptographic hashing. The 2nd question is about what involves in a masquerade attack on a network.
