Which statement about deception in SEW is correct?

• A. Deception involves misleading information or timing without necessarily overpowering the signal.
• B. Deception must overpower the legitimate signal to be effective.
• C. Deception is solely about spoofing ephemeris data.
• D. Deception cannot be used in space.

Answer: (A)

Deception in SEW is about shaping what the target believes by feeding misleading information or manipulating timing, rather than simply overpowering the legitimate signal. You can mislead receivers by spoofing data, corrupting metadata, or altering when a signal is received, so the operator makes wrong decisions even if the real signal is present. The key idea is credibility and timing—making a false picture seem plausible without needing to overwhelm the actual transmission.

That’s why the statement is best: deception doesn’t require overpowering the legitimate signal, and it isn’t limited to a single kind of data (like ephemeris) or restricted to space environments. In practice, deception can involve a range of tactics that distort what the receiver believes about where, when, or what is being received.
