Output status

Preliminary outputHuman review requiredNot certification
USE CASES

Where this instrument fits.

  • Avoid confusing PQC with QKD
  • Frame QKD as specialized infrastructure assessment
  • Explain PQC-first enterprise migration
  • Assess when QKD research may be relevant
INPUTS

Required input fields.

  • Environment (required): Ordinary enterprise IT, Critical infrastructure link, Research network, Special high-assurance point-to-point link
  • Communication profile (required): Internet/protocol-based, Metro fiber link, Dedicated point-to-point optical path
  • Infrastructure control (required): No optical infrastructure control, Partial, Full dedicated infrastructure
  • Primary goal (required): Broad crypto migration, Research evaluation, Specialized link security

Data handling: this interface uses the L2ET protected same-origin instrument engine. Do not enter confidential, regulated, privileged, incident, medical or sensitive operational data.

METHOD

Decision Tree logic.

Decision tree evaluates communication environment, infrastructure control and migration goal to recommend PQC-first, PQC plus QKD research or specialized QKD assessment.

Assumptions

  • QKD depends on infrastructure, operations and threat model.
  • PQC remains the ordinary software/protocol migration path.
  • Hybrid scenarios require expert review.
INTERACTIVE INSTRUMENT

EXAMPLE

Example input and output.

Example input

Ordinary enterprise IT using internet protocols with no optical infrastructure control.

Example output

Outputs PQC-first recommendation with QKD out of scope except research watch.

LIMITATIONS

What this tool does not do.

  • Does not design a QKD network.
  • Does not imply QKD replaces PQC.
  • Does not certify cryptographic security.

This instrument does not provide legal, medical, cryptographic, engineering, regulatory or compliance certification.
