A.
Availability

B.
Integrity

C.
Confidentiality

D.
Validation

Explanation:
Cryptography ensures the integrity of data, the confidentiality of the data and the validation of the sender and
receiver of the data. Cryptography does not ensure the availability of the data.
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:
B: Cryptography does concern itself with integrity of data.
C: Cryptography does concern itself with confidentiality of data.
D: Cryptography does concern itself validation (of the source and destination of the data).
