Preventing Arp Spoofing And Flood Attack

Fiber Optic Injection Attack

In this article we describe how fiber optic infrastructure based on PONs may be open to potential denial of service (DoS) attacks via optical signal injections. Security experts warn that this is a growing issue, which could take down entire sectors of PON segments. Unfortunately, the source is vulnerable to light-injection attacks, such as Trojan-horse, laser-seeding, and laser-damage attacks, in which an eavesdropper actively injects bright light to hack the source unit. The hacking laser could be a high-power one that can modify properties of components via. A well-protected and characterised source in a quantum key distribution system is needed for its security. Laser damage attack against. We experimentally demonstrate a power limiter based on single-walled carbon nanotubes dispersed in a polymer matrix.
