Which of the following does NOT concern itself with key management?

A.
Internet Security Association Key Management Protocol (ISAKMP)

B.
Diffie-Hellman (DH)

C.
Cryptology (CRYPTO)

D.
Key Exchange Algorithm (KEA)

Explanation:
Cryptology involves ‘hiding’ data to make it unreadable by unauthorized parties. Keys are used to provide the
encryption used in cryptology. However, cryptology itself is not concerned with the management of the keys
used by the encryption algorithms.
Modern cryptography concerns itself with the following four objectives:
1. Confidentiality (the information cannot be understood by anyone for whom it was unintended)
2. Integrity (the information cannot be altered in storage or transit between sender and intended receiver
without the alteration being detected)
3. Non-repudiation (the creator/sender of the information cannot deny at a later stage his or her intentions in
the creation or transmission of the information)
4. Authentication (the sender and receiver can confirm each other’s identity and the origin/destination of the
information.
Incorrect Answers:
A: Internet Security Association and Key Management Protocol (ISAKMP) provides a framework for security
association creation and key exchange.
B: The Diffie-Hellman protocol is a key agreement protocol.
D: Key Exchange Algorithm as its name suggests is used for the exchange of keys.
