Question 8 (2 points) ✓ Saved In Kerberos V4, the authentication field is of security benefit when asking the KDC for a ticket for Bob (i.e., in a TGS REQ message), but not useful when logging into Bob (i.e., in a AP_REQ message). True False Question 9 (2 points) ✓ Saved If an algorithm is discovered for quickly computing modular exponentiation, then the Diffie-Hellman key exchange protocol will become insecure. True False Question 10 (2 points) ✓ Saved A number of approaches have been considered to provide network security, for example, Kerberos, SSL, IPSec, etc. These approaches are similar in the services they provide and, to some extent, in the mechanism that they use, but they differ with respect to their scope of applicability and their relative location within the TCP/IP protocol stack. IPSec is a network layer approach, SSL is a transport layer approach, while Kerberos is an application layer approach. True False
