CyberRidge for Defense
Make sure your fibers cannot be hacked and are not being used as a vector for disruption
CyberRidge Carmel is a Photonic Layer Security system for defense fiber links. It turns the transmitted signal into optical noise at Layer 1, so anyone tapping a link between bases, command centers or allied sites has nothing usable to record. Its protection does not depend on the computational strength of an encryption algorithm, and it complements PQC and existing cryptography.
When there is Nothing to harvest, there is Nothing to intercept.
Secrets are protected throughout their lifetime
Whether that’s years or decades. Carmel’s protection doesn’t rely on the computational hold of any encryption algorithm.
Everything, kept under wrap
Headers and routing information are all buried, along with the payload, below the optical noise floor.
Transition to PQC safely
Migrating legacy defense systems to PQC takes years. Carmel can be rolled out link by link, securing the traffic that would otherwise be exposed during the migration window.
Sub-second key changes
Optical keys change multiple times per second and travel embedded in light, not stored digitally on the link.

How Carmel fits defense networks
Works over existing fiber
Runs on multi-vendor DWDM with EDFA and Raman amplification, alongside adjacent WDM channels.
Complementary to existing cryptography
Complements PQC asymmetric candidates, symmetric encryption, TLS and IPsec in a defense-in-depth architecture.
Zero latency
A physics-based solution that adds no latency to the link.
Air-gapped key generation
Encryption keys are generated in an air-gapped key generator.
Frequently asked questions
How can defense organizations protect fiber links between bases and command centers from interception?
Links between bases, command centers and allied sites run over fiber that can be tapped. CyberRidge Carmel turns the transmitted signal into optical noise at the physical layer, spreading it across a multi-terahertz spectrum and burying it below the optical noise floor, so there is nothing usable to record.
Why does physical-layer protection matter for data that stays classified for decades?
Harvest-now, decrypt-later collection targets data whose sensitivity outlasts today’s encryption. Carmel’s protection does not rely on the computational hold of any encryption algorithm, so traffic that was never recordable cannot be decrypted later, whether its sensitivity lasts years or decades.
Does Carmel replace PQC in defense networks?
No. Carmel complements PQC, symmetric encryption, TLS and IPsec in a defense-in-depth architecture. Migrating legacy defense systems to PQC takes years; Carmel can be rolled out link by link to protect traffic during the migration window.
How are encryption keys handled?
Encryption keys are generated in an air-gapped key generator. Optical keys change multiple times per second and travel embedded in light rather than being stored digitally on the link.
