Problem:
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
Additional Information:
These multiple choice questions is from Computer Science. The 1st question is about function of cryptographic hashing. The 2nd question is about what involves in a masquerade attack on a network.
