Why QKD; Why QuSAT

3

QKD is Quantum‐Safe today

QKD adds a layer of security (not exclusive!)

QKD from space removes the distance limitation of QKD

Good add‐on to our new tool chest!


Quantum Key Distribution (QKD)

• Point to Point: offered since 2007 < 100km

• Trusted Nodes: Longer distances and meshed networks

QuSAT: A Swiss QKDS project

5

Funded by the Swiss Space Office (SSO)• Phase 0 completed in 2016• Phase A kicked‐off on 1 May 2017• Phase A will last 12 months

A Partnership between:


Phase A: Two Objectives

6

1 - Technical

To design, develop and deliver a Quantum Key Distribution Service from space via a LEO satellite

Cost effective

Reliable

Secure

2 - Commercial

To develop a commercial business, offering the next generation data encryption capabilities

Strategic partnerships

Customer base

Private Equity


QuSAT driving ideas

7

• Keep the space segment simple

• Low cost

• Low cost User Terminals


• A Quantum Channel to exchange qubits between the satellite and ground user terminals, for a sufficient duration (3-5 min)

• A classical communication channel to extract secret keys from the qubits

• A safe key storage, management and distribution system

QuSAT Functional Requirements

8

Alice

Bob


• A Laser Communication Terminal (LCT), with an added

Quantum Channel Data rate: 1 Gbit/s

Diameter of the telescope: 10-15 cm

Pointing accuracy: <10 rad

• An Acquisition, Pointing & Tracking System (APT)

• A QKD Management System & a Hardware Security Module

(HSM)

• A Radio Communication Channel

QuSAT Technical Requirements

9


Assumptions:

• Eve cannot intercept the beam without being discovered

• Eve has limited technology (detector noise)

Physical Layer Crypto – Wyner wiretap

10


A new protocol: Quantum-Enhanced PLC

11

Assumptions:

• Eve cannot intercept the beam

without being discovered

• Eve only limited by QM

Advantages:

• Simpler systems at both ends

• More power


• T1: Lock‐in & clock synchro (<60 s)

• T2: Quantum Channel: qubits transmission (>180 s)

• T3: Keys processing & securityverification (…)
