Description Technique

Employment of true single photon source.

Laser Seeding Attack (LSA)

Use of true single-photon sources: Implementing quantum communication systems that can reliably produce single-photon pulses significantly reduces the vulnerability to PNS attacks.

Photon-Number-Splitting (PNS) Attack
