Show answer & explanation
Correct answer: C
The correct matching of the security concepts based on standard definitions is:
I. Message authentication → C: Verifies the sender's identity (Bond is sure Anthony sent it).
II. Message confidentiality → D: Ensures privacy (readable only by Bond, garbage to others).
III. Message integrity → B: Guarantees no alteration (arrives exactly as sent).
IV. Message non-repudiation → A: Prevents denial of origin (Anthony cannot deny sending it).
Correct Option: C (I - C, II - D, III - B, IV - A)
