Incorrect.
The correct answer is B) A cryptographic technique enabling multiple parties to jointly compute a function over their inputs without any party revealing their private inputs to others
B
Correct Answer
A cryptographic technique enabling multiple parties to jointly compute a function over their inputs without any party revealing their private inputs to others
Explanation
MPC (Yao's garbled circuits, secret sharing, homomorphic encryption): parties compute f(x₁,x₂,...,xₙ) and learn only the output, not each other's inputs. Used in private set intersection, privacy-preserving ML, and threshold signatures.
