50、Which of the following is BEST suited for secure communications within a small group?
A、Key distribution center
B、Certification authority
C、Web of trust
D、Kerberos Authentication System
ANSWER: C
NOTE: Web of trust is a key distribution method suitable for communication in a small group. It ensures pretty good privacy (PGP) and distributes the public keys of users within a group. Key distribution center is a distribution method suitable for internal communication for a large group within an institution, and it will distribute symmetric keys for each session. Certification authority is a trusted third party that ensures the authenticity of the owner of the certificate. This is necessary for large groups and formal communication. A Kerberos Authentication System extends the function of a key distribution center, by generating “tickets” to define the facilities on networked machines which are accessible to each user.
